If you brake is new. It’s only cause the piston are dirty. It’s happen to me. In my case it’s was dirty. I took some brakes cleaner. And clean my brakes and the pistons with the calliper with a soft brush. And then no more sounds. Check the pics. Thanks

Basically, there is no difference as far as what you can use. Put away all of the hype language on the bottle and focus on the DOT3. This is the main standard you need to look at. (Here's some easy brake fluid reading for you.) If your vehicle calls for DOT3, you should be able to use any one of the three you have listed. If it required DOT4, DOT5, or DOT5.1,...

I have had similar issues with a malfunctioning brake causing one wheel to get hot. One time it was caused by the tabs on the brake pads not fitting in the caliper properly. A little bit of work with a metal file allowed them to work properly. Another time it was caused by one of the caliper guide-pins becoming rusty and stuck. Cleaning and lubricating the ...

Possible causes: Overfilled reservoir. Warped disc or incorrectly installed calipers or pads (e.g. sliders not sliding). Do proper test of manually spinning the wheels jacked up. Engine off and on. Pads may touch initially, but wheels should continue to rotate a few rounds after you start them spinning. If not remove the wheels, check calipers can be pushed ...

The Bosch Automotive Handbook confirms that mineral-oil-based fluids are not hygroscopic: Mineral-oil fluids (ISO 7308) The great advantage of mineral-oil-based fluids is the fact that they are not hygroscopic, so the boiling point does not drop due to moisture absorption. It also makes clear that mineral-oil fluids are incompatible with systems designed ...

The front chamber is called a constant pressure chamber and holds constant vacuum. The rear chamber is called a variable pressure chamber, and varies from same vacuum as front chamber when no brake pedal is applied to atmospheric pressure when high brake pedal force is applied. The return force is provided by a return spring which pushes the diaphragm, valve/...

In all the VWs I currently own (5) pulling the e-brake causes the ECM to drop the throttle to idle.

The ABS system moves brake fluid around independently of the driver, so it may need a bigger internal cylinder volume to reduce the amount of "kick back" at the brake pedal. On some car models, the internal bore of the ABS and non ABS cylinders is different to accommodate the extra fluid volume, and the mounting points may also have different ...

Another possibility is that the small passageway in the master cylinder, which connects the working chamber within the master cylinder with the fluid reservoir above, is plugged. If that occurs, system pressure will not release when the brake pedal is released, and will gradually increase over time. This will affect the brakes on all four wheels. If, on the ...

Sometimes a flexible brake hose can develop an internal tear that acts like a one-way valve. This stops one of the calipers from releasing quickly or at all. Repeated brake application slowly buids up the caliper pressure and causes brake drag. If the blockage is not complete, then the caliper pressure will slowly release. If it drags while you are driving, ...
