Hi faslli,
Thank you for the donation.
When the calipers do not release sufficiently, it could be
1. Caliper pistons not returning. Check if the rubber boot is sealing correctly, any tear in the boot could result in water getting into the piston area and this would cause the piston to seize and not releasing.
2. Caliper slider bolts stuck. This would not allow the caliper to return but if this is the cause, the brake pads would have uneven wear, the outer pads would wear more or less than the inner pads by quite a substantial amount.
3. Faulty brake flexible hose. This would prevent the fluid from returning and heating would increase the pressure to lock the rotors. When the brake rotors are stuck, loosen the bleeder nut to see if the caliper returns when the pressure is released.
4. Handbrake cable improperly adjusted or stuck. Check the pivot at the caliper, it should return to the stopper area.
5. Faulty brake Proportioning Control Valve. If equipped with ABS, the accumulator could be faulty.
