hey guys just seeking some advise about my rear brakes

this seems to happen every time i get my car serviced. my hand brake doesn't seem to release the rear pads properly making a high pitched noise that comes and goes as well as a sound similar to when your pad are ready for replacement...

the first time the noise started when i got it back from a service and started to get worse day by day so i decided to replace the pads thinking that was the problem. doing so i noticed the pad still had life in them but thought iv taken them off might as well throw the new ones on anyways that fixed the noise as they seated themselves.

now i just got it serviced again but with the new pads still on it but they are still near new and knowing i haven't done 25000km as to what they said they will last for, i barely done 8000km, the same noise is back and is getting worse as the days go past and every time i use the handbrake iv taken the wheels off and i cant seem to find whats wrong.

any ideas on what could i do...also iv notice the service sheet did say i do require a brake system flush maybe this is the problem.

It could be that your handbrake cable might be stretched and the drums are not disengaging properly. To check properly you'd have to take the rear calipers and discs off to check how much remaining lining is left on the brake shoes.

I would say there is too much dust in the handbrake area behind the rotor, the mechanic is adjusting the hand brake and then causes the squeal

Best way to fix is remove rotors, clean the area off with water (dont use air) and then lubricate the back of the shoe with graphite greese

I had an issue where my handbrake would be stuck on and it was causing a squeal at high speeds but most of the time low speeds.

It cost me $500 to get new Handbrake cables fitted, and 4 different trips back to the mechanic to get it adjusted. These cars can be notorious for it due to their handbrake desgin.

Any word on the aftermath of the mechanic fix? Had a similar issue myself. Handbrake adjusted got massive low speed squeal. I'm positive I ended up changing my handbrake shoes, all four rotors and all 4 pads (no break fluid change though - silly i know), 12 months later my handbrake might need adjusting again! (is this normal?), hope it doesn't start again. if it does, I'm keen to hear what happened with yours so I have a potential solution

Also, when adjusting handbrake shoes. Back the cables off fully at the handpiece, then adjust through rear brake drums to specs. Then as a final adjustment, re-adjust at the handpiece to achieve good leverage. Alot of mechanics adjust at the cables only, and as a result it pulls the lever arms in the drums out too far. Alot of the time, the small pin inside the cylinder bore drops out or wedges sideways causing problems.
