Why does my car drag when the brake lock up?
Note that brake master cylinder and reservoir are closest to the front driver side. When the wheel/brake lock up, the brake pedal is stuck at the up position. Pressing with all my might wont make the brake pedal go down. The car drags and struggles to move forward or backward when it happens.
How to diagnose and fix brake drag?
The easiest way to diagnose this is to remove the caliper from the rotor and turn the rotor. If the drag still is present, then the problem is internal with the bearings. At this point, replace as necessary and reinstall to the proper torque value and pre-load.
What causes brake drag on the master cylinder?
Master Cylinder: Brake drag can be caused by an incorrect brake pedal adjustment. This pedal adjustment is crucial and if adjusted too tightly the vent port of the master cylinder can become blocked. The building pressure in the system results in brake drag and possible brake lockup.
What causes rear wheel lockup on Phoenix brakes?
The shoe lands or “bosses” are an often overlooked item when looking for the cause of a rear wheel lockup condition. The shoe lands keep the brake shoes square with the drum and provide a friction surface for the shoes to move against. Over time the bosses can become grooved and corroded as in Figure 61.6.

Why does my brake line drag after I release the pedal?
Brake Lines and Hoses: There may be pressure trapped in the brake line or hose after the pedal has been released. During brake application pressure is high enough to bypass the kink, but when the brake pedal is released, the spring pressure of the master cylinder is not sufficient for the pressure to bypass the kink.
