Do the Mk7 GTI Performance Pack and Golf R share brake pads?
Although the Mk7 GTI Performance Pack and the Golf R share identical front brake pads, front 340mm discs, and rear 310mm discs, they do not share the same rear brake pad. The friction surface is about the same, but the Golf R uses the electronic rear parking brake, and the pads have noticeably larger guide tabs with hooks.
What is the size of the brakes on a VW Golf?
The Front brakes are 312mm x 25mm Vented Discs, 54mm ATE single piston calipers The Rear brakes are 232mm x 9mm Solid Discs, Golf GTI 1.8T | Golf 130/150 TDI | Golf V5 150 | Seat Leon 130/150 TDI and 20VT The Front brakes are 288mm x 25mm Vented Discs, 54mm ATE single piston calipers
What kind of brakes does a GTI have?
The base GTI braking system utilizes 312mm ventilated front discs and 272mm solid (non-vented) rear discs, with single-piston sliding calipers at all four corners. These components are a direct carry-over from the Mk6 GTI, and both brake pads and discs are interchangeable between the late Mk6 GTI and base Mk7 GTI braking systems.
Should I buy performance brake pads?
if you go for the "race"option be prepared to get more dust, squealing/vibrations and accelerated pad wear and a harsh feel to the brakes - unsuitable for normal driving so thats why theres a range. buying performance brake pads will make a difference to your braking power, for not a lot extra cash over the standard pads.
Which brakes wear out the fastest?
Your front brake pads will also wear down faster than your rear pads. The front of your vehicle handles a lot more weight transfer as you brake, causing more wear. Over time heat and friction also contribute to brake pad wear.
Which brake pad wears faster inside or outside?
Inboard brake pad wear is the most common brake pad wear pattern. On a floating caliper brake system, it is normal for the inner to wear faster than the outer – but this difference should only be 2-3mm. More rapid inner pad wear can be caused by a seized caliper guide pin or slides.
Why would one side brakes wear faster?
Possible Uneven Brake Pad Wear Causes Front and rear brake pads naturally wear differently. When your vehicle is moving, the forward momentum tends to put more strain on the front brakes, which can cause them to wear faster than the rear brakes.
Why are my driver side brake pad wear faster?
The slide pins are the metal pins that allow the brake caliper to slide back and forth with the wheels. When these pins become corroded, the caliper can no longer slide. As a result, the caliper becomes stuck in one position; if it sticks in the right position, it can cause the pads to wear more quickly on that side.
How do I know if my front or rear brakes are bad?
Front or Rear?While driving, slowly brake and listen out for noise.Repeat this step, this time using your emergency brake.If you hear a noise while braking normally, it's likely that the issue is with your front brakes. If you hear a noise while using the emergency brake, then it's the rear.
Why would my rear brakes wear before front?
The one rear brake pad worn to metal contact can be from a variety of reasons. Some reasons could be a sticking brake caliper piston, dirty and sticking brake caliper slide pins or a restricted brake flex hose, to name a few.

How do you know if your caliper is sticking?
7 Symptoms of a Brake Caliper Sticking (and Common Causes)1) Car Pulling to the Side.2) Brake Pedal Stays Down.3) Brake Fluid Leakage.4) Hard to Stop Vehicle.5) High Pitched Sounds.6) Difficulty Steering.7) Burning Smell.
What happens if I only change one side of brake pads?
BUT, the brake pads should ALWAYS be replaced on BOTH sides, AT THE SAME TIME. If you only replace pads on that one side with the new rotor, then you will run into the same problem later on, but on the other side.
Are rear brake pads thinner than front?
On top of that, because rear brake pads typically deal with less force than the front ones, they're usually thinner. Combined with the electronic stability control and traction control, and you have accelerated rear brake pad wear.
Do rear brakes do anything?
How Do Rear Brakes Function? Rear brakes typically handle less than 40% of the braking force, so they don't generate as much heat as the front brakes. The rear brake is designed to provide stability, or else they would lock up every time you hit the brake pedal.
How to improve brake power?
If you want to improve your braking power on a budget, try using a Performance brand of Brake fluid and bleed your brakes. it makes alot of difference!
Why are front brakes always bigger?
This is because under braking the front tires offer increased traction as weight is transferred forward. This additional traction can be utilized by increasing the brake force applied to the front axle vs. the rear. The outcome is a bias split that is more in the order of 70 front/30 rear resulting in shorter and more controlled stops.
How does air travel on a disc?
For solid discs, all the air travels over the surface of the disc - the same surface as the brake pads. For vented discs, a considerable amount of air flows through the interior. Because it's spinning so fast, it creates a vacuum and air is sucked into the center of the disc and forced out through the edges.
Why are straight vanes so popular?
Straight vanes are the most common because they are easy to manufacture.
What is grooved disc?
Grooved Discs. Grooved discs keep the pad surface clean and allow certain gasses to escape which improves performance. not too many grooves though, you only need 6 or so, any more and it it just for looks (e.g tarox cheese graters) For street driving they may make a marginal improvement in initial brake "bite".
What are the advantages of two piece discs?
Two piece discs have several advantages including lower weight while maintaining most of the heat capacity and better cooling by having a more open centre section . Two piece discs increase costs and generally a poor choice for street cars. For racing, they are great!
How much does upgrading rear brakes do?
Upgrading the rear brakes does not do much in terms of braking power, reducing your stopping distance. The rear brakes only account for about 30%. Most people upgrade just for looks.

I’ve also tested the theatrical idea of the ACC uses only the back brakes and that didn’t pan out.
SpursMadDave
Yeah depends on how ACC and traction control etc work, rear pads on my Jag wore out VERY quickly it varies from car to car, I wouldn't be too concerned personally Sent from my SM-G935F using Tapatalk
Andygo
I'm not that concerned actually, just goes against every other car I have owned, especially as the rear tyres are in pretty good nick still.

My rear disc's look terrible. But apparently they still have lots of life left. (At least thats what they said at the MOT)

Mine looked scored only a few months after getting the car and at the first service they were given a red status at the health check. When I got rid of the car at 3 years, 32k miles the rear pads were virtually worn out. Every car we’ve owned with an electronic parking brake has consumed rear pads quicker than fronts.
Who makes cross drilled brake discs for Mk7 GTI?
High-quality cross-drilled brake discs for the Mk7 GTI are available from Stoptech and Zimmerman .
What brakes does a GTI have?
The base GTI braking system utilizes 312mm ventilated front discs and 272mm solid (non-vented) rear discs, with single-piston sliding calipers at all four corners. These components are a direct carry-over from the Mk6 GTI, and both brake pads and discs are interchangeable between the late Mk6 GTI and base Mk7 GTI braking systems.
Why do I feel a warped disc in my car?
Warped discs or rotors are usually the result of uneven brake pad deposits on the disc surface , which can be caused by any number of things. First, low quality, low-carbon discs will heat and cool unevenly as they’re used, causing ‘hot spots’ on the disc surface. The brake pad material will stick to the hot spots, causing a high spot on the surface and that feeling of a warped rotor.
How many brake pads does a GTI have?
All factory GTI brakes use a single-piston caliper on slider pins, with two brake pads per disc. The brake pads are held by the caliper carrier and are specific to the caliper and size of the disc being used. Brake life on the Mk7 GTI varies greatly depending on the driver and conditions the car sees regularly.
Why do my brakes squeak on my Mk7?
Squeaking or squealing brakes on your GTI results from the brake pad vibrating at an audible frequency. This could be due to uneven wear, improper break-in, or external dirt, dust, and debris creating issues. As long as the pads have plenty of material, the discs are not obviously worn or damaged, and the car is still stopping as it should, squealing brakes may be annoying, but they are not a requirement for replacement. It’s also worth noting that more aggressive higher performance brake pads are more likely to be noisy.
How often should I change brake fluid on a Mk7 GTI?
Brake fluid capacity is approximately 1.2 L (1.3 qt) and should be changed three years after delivery and every two years after that point.
What is a Mk7 GTI?
The Mk7 Volkswagen Golf GTI brakes are based around an evolution of over revolution concept, ensuring cost-effective and reliable performance for the sporty hatchback. By utilizing many components from the outgoing PQ35 Mk5/6 chassis, along with some new MQB-specific parts, the Mk7 GTI offers excellent braking performance with very little required maintenance. Because of the modular design, there are many upgrades and aftermarket braking options as well, including some ‘big brake’ options from the higher-end Audi RS and Porsche models.
Why does my front brake go out faster?
The only time this happens, in my experience, is when the adjustment is wrong! By the nature of dynamics the weight gets transferred forward thereby putting more load on the front brakes so these were out faster.
Why do cars have rear brakes?
It used to be more common to use the front with just a little rear braking. This was due to cars not having ABS/stability control systems. Now that cars have all that tech they are less likely to spin out if the rear brakes grab sooner. Thats done so the car stops more flatter instead of nose diving. Plus rear brakes are usually thinner than front so even working the same the rear will not last as long. So its mostly a comfort thing that can be taken advantage of due to newer technology. I already replaced the rear brakes in my SiLs Lexus but her front still look good.
Why do Volvo cars use the same pads?
Several possible reasons: 1. AWD car and DSC is set up aggressively. 2. (more probable) in order for company to save money, they use same pad on various models. VW does that a lot where rear pads on my Tiguan are same as rear pads on 1988 Golf GTI. However, difference is some 1500lbs between two vehicles. It could be that Volvo is using same pads on S60 and some smaller models or models that are out of production. 3. Check pistons on calipers.
What happens if you have a lot of force in the back of your car?
If you have a lot of force in the back, there is probability that rear end will pass front end in slippery conditions. Usually brake force if 70/30 and there is reason for that, and that is simple dynamic.
Do rear brakes wear out more when driving?
I was always taught that rear brakes may wear out more with around town driving, as the rear pads are applied first to slow the shift forward. My sisters car always kills rears, shes always ripping around town stop to stop, while my moms last much longer in the rear as opposed to front with her mostly highway driving.
Do rears wear out before front?
The only time I have ever had the rears wear out before the front was with a stuck caliper. Make sure the sliders are lubed properly.
How thick are GTI rotors?
Turns out the GTI w/ PP rotors are 5mm (25 vs 30) and 10mm thicker (10 vs 20) front and rear respectively. I think that may not work with the TDI's stock calipers unless there's that much travel in the piston to allow that large of a variance especially in the rear?
What is the bore size of a GTI?
the Golf Bore size is 23mm with a pushrod length of 1.64", front caliper piston is 54mm. The GTI Bore size is 25mm with a pushrod length of 2.05" (both 312mm and 340mm brakes), front caliper piston is 57mm (312mm) and 60mm (340mm)
How to remove a rotor from a car?
1) raise vehicle and remove wheels. 2) remove 2 - 21mm bolts that hold the carrier to the spindle and pry the caliper away from the rotor and set out of the way. 3) remove the 1 - T30 screw holding the rotor, then three more T30 screws holding the dust shields to the spindle.
Does the 18Z have larger rotors?
The 18z does allow slightly larger rotors which likely makes up for the smaller piston area... assuming similar pad area. FWIW, both were are speced to stop the same size vehicle.
Does the MK7 Golf have brakes?
The brakes are fantastic on the MK7 Golf, just want a bit more to fill the wheel up and also will be doing a few autocross events in the future, so this won't hurt.
Is the master cylinder made for piston calipers?
the master cylinder isn't made for the larger piston calipers on the performance pack.
Is the master cylinder mismatched?
It's mismatched with the stock master cylinder. It's so undersized for those brakes it takes a lot more pedal travel to move to appropriate brake fluid to push the pistons.
