Brakes Pulling or Locking Up

o Distorted discs
o oval drums
o Poor use or use of wrong transmission fluids
o Broken brake wheel cylinders, drum plates or calipers.
o Worn out caliper pistons.
o Damaged ABS system

Check the caliper pistons for damage. Remove the caliper from the disc and pump the brake pedal repeatedly to push them out of the corroded area. Simply disassemble and rebuild it. Rebuilding usually requires cleaning and replacing the rubber parts and sometimes the piston itself. Most times, the degree of damage may require you to remove and replace the caliper totally. Please ensure you do so to avoid risks of another lockup, especially on a drive.
