Just like with the master cylinder not releasing causing the brake drag, a caliper not releasing and staying applied can do the same thing. If only one position is dragging, this could be the case.

What causes brake drag when replacing master cylinder?

This situation is usually remedied by replacing the master cylinder. We see a lot of brake drag problems caused by a master cylinder that is too full of fluid. If the system is overfull, there may not be enough room in the reservoirs for the fluid to return.

Why does the brake pedal go down after replacing the rotor?

When you compress the caliper, this leaves a gap between the brake pads and the rotor. If it didn’t, it would be very hard to get the new pads/caliper back onto the rotor. So, when you first get behind the wheel, you need to pump the brakes several times to get the caliper piston to the point it is pushing the pad against the rotor.

What to do if your soft brake pedal is leaking?

Pump the pedal gently and then hold the brake pedal. If while holding the pedal it starts to creep downward, you more than likely have a master cylinder that is leaking internally and not able to keep pressure at the necessary amount. Replacing the master cylinder followed by bleeding the brakes will usually cure this problem.

What kind of brake pads do I need for Bratbus?

For Bratbus, remember that you pushed the pistons all the way back into the calipers, so it’ll take a few pumps to seat the new pads against the rotors. What brand pads/rotors did you use?
