I had the rearend worked on in my truck 3 months ago...and while they were at it they said they would do a rear brake job since they had to take it apart anyways. My dad was the one actually getting the work done...he was driving the truck at that time. Anyways, he let them do the rear brakes which included shoes and wheel cylinders (invoice:
replace rear shoes, rear wheel cylinders). So I started to drive it since then. Well, maybe it started a month or so ago, the brakes started feeling weird...every once in a while the pedel would have less pressure. It got worse and worse and I started loosing brake fluid bad. It was leaking out of one wheel. Finally got bad enough for me to take a look a week or so ago.
It was leaking out of the wheel cylinder that they were suppose to replace. I took it off and took the cylinder apart. Turns out one of the seals in the cylinder was reversed...the lip of the seal was facing the wrong way, causing it to leak.
So now I am wondering if they just put kits in the wheel cylinders....

...unless one of the new cylinders came assembled wrong. I can't say that the wheel cylinder itself looked new...kind of dirty, rusty looking, but that could be from the two months of driving...??? The shoes were replaced though.
Should I go back and explain what they did? I would have taken the truck to them in the first place, but I didn't want to risk driving that far with a bad wheel cylinder. What would you guys do? I was thinking that this could have been a liability issue...if I was to get in a wreck because of my brakes. But then I guess its my fault to not figure out the problem when I noticed the brakes acting weird.
The shop that did the work has a 12 month guarantee 100% on parts and labor. Should I try to get the money back for the brake job...since they were suppose to replace the wheel cylinders completely, not just rebuild them. I don't know...any advice would be helpful.
Sorry for the long post.
Thanks
