brake work/ebrake question?

[Greyd]

So I had some work done on my rear brakes about a month and a half ago. They replaced pads, did some work on the rotors. Would this in any way affect the ebrake?

Apparently my ebrake is totally broken right now and as of right now, they are saying that they are probably not responsible for the ebrake issues, because they work they did have nothing to do with the ebrake.

Any ideas?

It could, but it is pretty hard to do.

What car do you have? Some cars' e/hand brake uses a drum even if the primary rear is disc and others (I think most but not sure) use the same braking surface.

In any case was the brake perfectly fine when you first left them?

If you have a rear brake that uses the same friction surface for hand brake as primary then it has to be disconnected when you change the brake.

What exactly does "totally broken" mean?

It could be the cable simply came off. On my '91 Grand Prix, the e-brake worked by pulling on a lever on the caliper and pulling the pads together. The cable's saddle was simply just pulled over the lever. It would be easy to miss this. Pull off a rear wheel and have someone move the e-brake and look for cable movement. Likely, you'll be able to figure out what happened quickly.

I have an 05 Acura TL. Supposedly what happened was that the pin that held the assembly off the rotor fell off or broke and caused the whole ebrake assembly to come in contact with the rotor.

That model acura uses a drum that is part of the rotor its all one cast part. the shoes are held on by pins and retainers just like traditional drum brake shoes, the tension pins tend to rust and become weak so that when you pull off the rotor, the park shoes grab at the slightly rusted up drum surface and pull out of the retainers.

if they dont pull out all the way, they will pull enough to be severely weakend and will fail shortly after reassembly.

the question here is, did they pull the rotors and machine them, or replace the rotors? or did they just do a "pad slap" and send you on your way.

if they did anything to the rotors, then they most likely caused this issue if it was the tension pin that failed, if they didnt do anything to the rotors, then they were not at fault for this failure, although they should have resurfaced the rotors if they replaced pads.

if the failure was the connecting rod or other parts, its difficult to say without seeing the actual condition of the parts...(failure analysis was part of my job for many years diagnosing other techs comebacks)

this man speaketh the truth.

assuming he is right about that car using a drum ebrake (i have no idea), i would definately blame the shop if the ebrake worked before, they machined or replaced the rotors, and then it failed to work. if they pad slapped it (common on rear brakes), it would be hard for them to mess it up unless the mechanism is in the caliper.
