wheel cylinder replacement

I was experiencing often (75%) a loud clank in the rear when breaking. I took it to the dealership where i bought it on two separate occasions and they said they couldn't duplicate it. always when I left it was there again. Finally I took it to another chrysler dealer and they found the rear wheel cylinder is leaking and turns out its covered under my warranty (surprise). In the meantime, i get a call from them that I need rear brakes. I told them that i wasn't planning on paying them 100+ dollars for a job i can do myself. They called back and said they couldn't do the job unless they replaced the brakes and that I'd have to bring it back after it's done.
Is this right?? and if i replace them and bring it back up there, will the new brakes be ruined from the leaking brake fluid??

If the brake fluid or any oil contaminates the linings, it will shorten the lining life. The heat and solvents break down the resins in the lining and delaminate the material from the shoe if it is a bonded lining. It can also cause cracking in the lining material.

It is impossible to clean a contaminated shoe!! All such attempts do is delay the inevitable replacement to fix a grabby or otherwise problem brake operation.

If they are going to do a proper job for only a $100 bucks extra, I would consider the benifit of the saved time and the "warrenty" on the work they do, what ever that will be against what ever it cost you to replace the parts yourself.

Also, if the one wheel cylinder is leaking, what is the condition of the other??? Consider inspecting and rebuilding it at the same time if you arn't already....

Okay...Both cylinders are leaking. The dealer wants to charge me $100 for the brake job, which I can do for the cost of the brakes alone. The actual work to replace the cylinders is not costing me anything.
I guess my question is, is it necessary to replace the brakes BEFORE replacing the cylinders.
It seems to me that it would be logical to replace the cylinders before replacing the brakes so that they don't get leaked on......

It seems they might be using the liability lever to get you to spring for the extra work.

The cylinders should be fixed first.. Look at the axle seals at the same time then the shoes can be replaced with a prospect of a long life. What about the drums and the other hardware (springs etc.)???

Suggest that you bleed the brakes till the new fluid runs clean at the wheel cylinders and at the calipers too.

What would they say if you asked them to supply the 2 wheel cylinders and maybe the shoes too and you would let them off the hook for the install. That should satisfy both you and them.

Just a suggestion........

if the wheel cylinder ruined the brakes and they are going to warranty the wheel cylinder,they could warranty the brake shoes that it ruined.
