VW Golf - Brake Fluid Reservoir Overfilled after Fitting New Brake Pads and Discs


I recently replaced the brake discs and pads on my VW Golf. This weekend when using the car I found that the front brakes seemed to make a grinding noise when driving and more so when braking. On further inspection the brake fluid reservoir was overfilled right to the top of the container.

Obviously when the new pads were fitted and the callipers piston retracted it must have pushed more brake fluid out back into the reservoir.

After fitting the new discs and pads the brake fluid reservoir was completely full and well above the MAX marker line. I used a syringe to remove brake fluid from the reservoir and took out around 40-50ml before it got back down to the maximum marker level.
