Jump To >> How to prevent rear VW brake pad squealing.
Most front VW brake pads have wear sensors built right into the brake pad material. If you see the VW brake warning light illuminated on your dash board instrument cluster, you have approximately 3,000 miles left on your front pads and VW brake rotors. It's usually less than 3,000 miles if you're hard on the brakes, which most of us are. When you see this light go on VW brake repair service is in the near future.
The rear VW brake pads don't include wear sensors and thus, won't cause the rear VW brake pad warning light to come on. The main indication of worn rear VW brake rotors is a grinding metal-on-metal sound coming from the rear of the car every time you depress the brake pedal. When the rear 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 repair service immediately when you hear this grinding noise. Usually these symptoms occur when there is between 40,000 to 80,000 miles on your brake pads and rotors.
It is important to know that new rear VW brake pads should be bedded in carefully. When new brakes are installed, you need to go easy for the first 150-200 miles. Some customers were perplexed after installing a new set of rear VW brake pads and rotors because they were experiencing squealing. They have commented that their brake pedal "just doesn't feel quite right." What's causing this?
Typically, all replacement brake rotors after being manufactured are stored and shipped with an oil or cosmoline applied to the brake rotor face. This is done to prevent rust during storage and transport. Often, when it comes time to install the brake rotor, the rushed mechanic doesn't take the time to remove this residue believing it will "burn off" right after you apply the brake pedal a few times. It is important to understand that if oily residue is left on the brake rotor face you will potentially ruin your new rear VW brake pads and rotors. Why? Because the oil residue will embed itself on the new rear VW brake pads and become "glazed." This causes them to "slip" instead of "bite" into the new brake rotor face. The glazed brake rotor or brake pads generate more heat when slipping and do not allow for the proper brake rotor and brake pad break-in conditions to take place. This condition will, as well, cause the brakes to feel weak when you push on the pedal.
New rear VW brake pads shouldn't be used with old brake rotors (visa versa). Why? The surface area of a new rear VW brake pad must come in contact with a flat/smooth rotor, free from imperfections (see image below). The face of an old brake rotor is imperfect and has a glazed and scored surface instead of a flat/smooth surface. Using old brake rotors with imperfections will not allow the new rear VW brake pads to be bedded in properly. This will result in weak braking performance and rear VW brake pad squealing. Therefore, always install new brake rotors when installing new rear VW brake pads. That is why Blauparts offers rear VW brake pads with rotors in one convenient kit to ensure successful brake repair.
Are you experiencing pulsing through the brake petal when applying the brakes? Or a shuddering vibration through the car when braking? Brake replacement is often conveyed as a simple service. Some chain "we-fix-everything-for-less" repair shops focus on turn around – rather than the quality of a brake job. Just slap on a new pair of rotors and pads? Not necessarily. Assuming that it's as simple as warped rotors could end up costing you more money in the long run. Why?
Tips on how to ensure correct rear VW brake pad replacement.
INSPECTION Road conditions, age, and resulting rust and pitting affect a lot more than just the rotors and pads. Brake rotors and pads are just two parts of a comprehensive braking 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 particular VW or VW model.
Before investing in brake repair be sure to properly inspect all brake components, in particular the following:
- Caliper piston, which is located under the caliper piston boot. Look for any pitting or rust. If you note any pitting or rust behind the boot, the caliper should be rebuilt or replaced.
- Check the brake hoses for any signs of age or splitting.
- Confirm the integrity of your brake fluid, it's color and age.
- Confirm brake master cylinder functions. Example: Use an infrared heat gauge to look at the temperature of each rotor after a test drive. A temperature difference often points to an underlying issue on a particular side that may require a more detailed inspection.
SURFACE PREPARATION Common premature brake issues after brake rotor and pad replacement are usually caused because one of the following areas were not properly cleaned. Be sure that they are free of all debris, rust, grooves, pitting, sharp edges, and are just like new:
- Wheel hub [IMAGE 1]. If the rusting and pitting is horrible the hub should be replaced. If it isn't replaced, the new brake rotors won't ride 100% true. Use a brake hub and rotor True Gauge Tool to confirm correct brake rotor alignment.
- Brake pad to caliper mating surfaces, the caliper piston, and outside of caliper [IMAGE 2, IMAGE 3]. This allows the new pad to ride true to the caliper piston.
- Brake caliper pins [IMAGE 4].
- Brake pad to carrier bracket mounting points / contact points, where the pad slides on carrier bracket [IMAGE 5, IMAGE 6]. Usually a medium grit scotch brite pad is sufficient to achieve smooth surfaces. If pitting is really bad a minor file might be needed.
HELPFUL TIPS Apply light grease to the brake carrier contact areas to slow down rusting. Lightly apply anti seize to the clean hub to slow down rusting. Lightly grease the caliper carrier pins [IMAGE 7].
PICTURED EXAMPLE: 1 previous owner 1997 VW A4 with approximately 100,000 miles on it. Service records indicated this was the 2nd brake service performed since date of sale. Note the debris, rust, grooves, pitting, sharp edges. It's important to take the time to properly clean all contact areas and make them just like new.

Why Choose BLAU®?
VW customers are always concerned about too much rear VW brake pad dust or squealing. During braking, kinetic energy is converted into heat. If you brake too hard during the 'running-in-period', the rear VW brake pads heat up too much. The uncured bonding agents emerge at the surface where they cause considerable hardening to the rear VW brake pads. A single panic stop creates friction resulting in scorching temperatures approaching 1,000°. Our rear VW brake pads excel in precisely these performance street, high speed, high heat circumstances. With every brake component of your vehicle pushed to the maximum, the rear VW brake pads in our VW brake kits deliver consistent, efficient, smooth, quiet braking operation. Designed to control your speed by delivering quicker, more consistent stops, while combating brake dust and squeal. Depending on your driving style, the life expectancy of these rear VW brake pads can exceed other conventional organic rear VW brake pads by 200% - 500%! That is why we call them performance street rear VW brake pads. Please Note: High quality rear VW brake pads reduces, but doesn't eliminate the need for braking in new brake pads. When new brakes are installed, you need to go easy on them for the first 150-200 miles
