Hey, I have replaced both rubber brake hoses on the front both front calipers both pads and rotors, bled the air out of the system but the front calipers are still sticking to the rotor. What could still be causing this? They are sticking just enough to keep the brakes hot and make them squeal and squeak. When you left the wheel up you can spin it by hand but when you stop spinning it it immediately stops. What could still be causing this?

Hi Alec@1993,

We can help with this information. Was there any prior work performed before you replace parts, was it breaking prior? Let us know what happens and please upload pictures or videos of the problem. Are both sides breaking,
Check out the diagrams (below). Follow these bleeding instructions. Cheers, Nick

This happens when the brake booster push rod is adjusted out too far which does no allow the brake master to return fully holding the brakes on. To confirm the issue loosen the brake master mounting bolts 3 turns to see if the car starts to roll again, if so remove the master and adjust the booster push rod inward. Also a brake flex hose can come apart internally causing a short of check valve in the system but this is usually isolated to one brake either front or rear.
