Slotted & Drilled rotors offer a compromise, midway between the benefits of slotted rotors and drilled rotors.More items...
Do rotor sizes matter?
The simplest brake upgrade, to gain sheer stopping power, is upsizing rotor size. You can exchange brake pads, experimenting with different material compounds for feel and durability, but rotor size has a much more significant influence on absolute brake performance.
How long do VW rotors last?
30,000 - 80,000 milesThe answer depends heavily on the conditions of your everyday commute, your driving style, the type of rotors, and the type of vehicle you're driving. Frequently, VW Golf rotors need to be replaced every 30,000 - 80,000 miles depending on the factors above.
Is it cheaper to resurface or replace rotors?
Resurfacing these rotors with an on-car lathe can virtually eliminate runout problems, but it requires investing in the equipment. Some installers tell us it's cheaper and easier just to replace the rotors.
Can I put bigger rotors on my car?
Just installing larger rotors won't do anything for performance and you may have clearance issues with the smaller caliper brackets, not to mention out of spec rotor wear that might cause braking issues. If you want to change rotor size, you should be installing calipers to match.
Can I put thicker rotors on my car?
Yet, you should never only upgrade to bigger rotors. You should also upgrade your brake pads and calipers. A bigger rotor has more surface area for the pad to rub against. Using the original pad would be wasting some of the rotor surface.
Are drilled rotors better than solid?
If you live in an area that experiences a lot of rain, drilled rotors are a very good choice. They perform well in rainy climates by offering a good “wet bite,” hold up well over the life of the rotors, and deliver more friction and more bite than their slotted counterparts.
Do I need 200mm rotors?
For aggressive enduro riders with large 29” wheels, 200 mm rotors are mandatory and upgrading to 220 mm rotors is worthwhile for heavier riders. Trail bikes also benefit from powerful brakes. Unless you've got powerful brakes such as SRAM CODEs or a four-piston Shimano model, we would always resort to 200 mm rotors.
Are front rotors bigger than rear?
Front rotors are typically larger and thicker than rear rotors, and they're also more expensive. This is because front rotors endure more wear and tear than rear rotors. In this blog post, we will discuss the differences between the front and rear rotors, and how you can tell which ones your car needs to be replaced.
Why are bigger rotors better?
Larger rotors have a greater mass and allow for greater storage of heat. This is good because if there is a greater capacity for heat in the rotors, your brake pads and hose fluid can stay at operation temperatures.
Can my rotors be resurfaced?
Resurfacing Your Rotors Sometimes your rotors may need to be resurfaced because they have worn unevenly, warped from heat, or become damaged by worn brake pads or pitted from corrosion or rust. Resurfacing rotors removes some of their metal, until the surface is smooth and even again.
Are rotor resurfacing worth it?
In the long run, it's likely less expensive to replace your rotors when there are consistencies in the face of the rotor. New rotors won't wear as quickly on your brake pads as damaged rotors, and resurfacing the rotors means you'll only get one last "hoorah" out of them before they need to be replaced anyway.
How much does it cost to resurface rotors?
Resurfacing cost per rotor can vary widely. If you remove your rotors yourself and take them to a shop or parts store for resurfacing, the cost can range from as little as $15 to over $45 per rotor. To have a repair shop remove, resurface and reinstall your rotors can cost up to $100 per wheel, $400 for the whole car.
Is it necessary to resurface rotors?
Those severely damaged rotors usually need to be replaced, not resurfaced. Some vehicle manufacturers even require that you replace your rotors rather than resurface them. Otherwise, most industry experts suggest that you should replace them every 30-70K miles.
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 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!
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".
Why are my discs warped?
if your discs are warped its because you have heated them up too much during hard breaking. probably knackered but you might be able to get them skimmed.
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.
Do brake discs wear out faster?
Drilled discs generally wear out brake pads faster and produce much more brake dust as a result.
Is a 5kg disc better than a solid disc?
This increases the surface area of the disc and allows air to cool the disc mass more effectively. A 5Kg vented disc will cool much quicker than a 5Kg solid disc. In many cases, a vented disc can weigh less than a solid disc and still provide more effective braking because of the cooling effects alone.
How Do You Know If Your VW Brake Rotors Need to Be Replaced?
This is typically why the front braking system is always larger than the rear and why the front brake rotors and brake pads will need to be replaced more frequently. A telling sign of needing new front VW brake rotors is indicated by the brake warning light being illuminated on the dashboard instrument cluster. Most front VW brake pads have wear sensors built right into the brake pad material. This wear sensor triggers the brake warning light to illuminate on the dashboard instrument cluster. With the brake warning light illuminated, this means the brake pads are worn and at the end of their life cycle. Due to the higher performance expectations of today’s modern cars your brake rotors typically should also be replaced with the brake pads. If you are experiencing the brake warning light being illuminated your VW brake rotor and brake pad should be replaced right away in order to restore and maintain proper road safety and braking performance. If you are not sure if the front of your vehicle has brake wear sensors a second way to see if you need new brake rotors is to visual inspection the condition of your brake rotors and brake pads. A third indication of worn front VW brake rotors and pads is a grinding metal-on-metal sound coming from the front of the car every time you depress the brake pedal. When the VW brake pad material has been fully exhausted, contact with the VW brake rotor will cause this type of grinding sound. You should seek an VW brake replacement service immediately when you hear this grinding noise.
How many miles do you need to go to install new brakes on a VW?
When new brakes are installed, you need to go easy for the first 100-200 miles. Some customers were perplexed after installing a new set of VW brake rotors and brake pads because they were experiencing squealing. They have commented that their brake pedal "just doesn't feel quite right." What's causing this?
What are the parts of a brake system?
The braking system's main components include: Brake rotors, brake pads, brake hoses, calipers, caliper carrier brackets, caliper guide pins and boots, brake pad retaining clips, hoses, wheel hubs, brake fluid, brake master cylinder, etc. Spending the extra time and money to properly inspect and diagnose the root cause of brake problems before diving into repair is imperative. Some owners just throw a new pair of rotors and pads on, only to have their symptoms return shortly thereafter. Make sure you choose a reputable ASE certified mechanic that is familiar with your VW model.
What happens if you use old brake pads?

What happens if your rear brake system does not have brake wear sensors?
If your rear brake system does not have brake wear sensors you will not experience the VW brake pad warning light on the instrument cluster dash area . You will need to do a visual inspection for the condition of your brake rotors and brake pads.
How to tell if you need new brakes on a VW?
A telling sign of needing new front VW brake rotors is indicated by the brake warning light being illuminated on the dashboard instrument cluster.
How to find rotor size?
Call your local OEM dealer and ask for the original rotor sizes or OEM rotor/pads part numbers based on your vehicle’s VIN number (VIN# is referenced in your ownership papers). The dealership may not tell you the rotor size, but they will give you the genuine part numbers for your vehicle. You can then shop at other sources using those part numbers. However, if your car has been upgraded with HD/performance brakes at a later date, the dealer would only know your original factory configuration and would be unaware of this upgrade.
When will rotors be available for 2020?
August 15, 2020. More often than not, there are multiple rotor & pad sizes available for a given model. These sizes are not interchangeable, and you must get the right one to fit on your car.
