Hoping someone can help this one.
I have a 53 plate mondeo with a sticking rear caliper causing the handbrake to fail on one side. I'll keep this short, the handbrake stuck on causing the wheel bearing to overheat, requiring a new wheel bearing. This was replaced along with new pads and discs but I still have the issue with the caliper siezing, although as the handbrake is not working on this one side it doesnt stick the handbrake on causing it to overheat - again.
When I fitted the new pads I wound back the piston on the caliper. When I checked the other day I can see that the piston has wound out, yet the handbrake arm on the rear of caliper will only move back and forth with brute force (hammer).
Could it be that the piston is getting stuck halfway out due to corrosion? If so, can these things be cleaned up and refitted or is it simpler to buy a new part?
I thought is was the handbrake cable which attaches to the caliper, which in turn pulls the arm which pushes the piston out - is this correct?
Any guidance appreciated as MOT is looming.
