Rear Caliper

[calvin0325]

So I get up this morning to go to the base for Physical Training (PT) and it is a little cold (24F). I get in and fire up the SHO and let it warm up for a few minutes to get the frost off the windows. So, a few minutes later another one of the soldiers that rides with me show up and we are off. About 3 miles into the drive the brake light on the dash flickers on then back off till I hit the on ramp to the Autobahn (60 mph section to base) when it comes back on and stays on. So I am like WTF now.... So I get up to the exit ramp for base and I got brakes still....good thing as its a coverleaf style ramp, anyways I get up and onto base and I get out to check it out and I still had a half a reservoir of flluid but the rear tire on the inside is covered in fluid. I figured it was probably a brake line but having just gone over the cars brakes I knew the lines were in decent shape. So I start looking even more only to notice the fluid is running down the backside of the rotor from inside the caliper piston area. What the .... would cause a 6 month old caliper to start leaking there? I have never seen one leak like that on a newer caliper. Only on a SHO !!!! But then again...at least it wasn't the lines in the middle of winter. One of the only cars I know that would put a rich man into bankruptcy.

I had the pads fall out once because one of the slider pin bolts fell out. This caused the piston to over extend and rupture. Blue loctite them slider pin bolts

that was the first thing I thought of....when I looked at in the bolts are all still in place and the pads are still there...but fluid is coming out from in the piston area...

Well it must be blown. Was it a new caliper or rebuilt? FWIW the one that fell apart on me was an AZ rebuild and they gave me a new one because of the lifetime warranty.

was a Raybestos new in the box .....I am sure I will get one as I sent them a message last night about it.....

 

[SHOZ123]

Good luck. I bought some Raybestos Brute Stop rotors that were guaranteed for a lifetime. After a year they developed radial cracks. I was told the lifetime was while they were still in the box......

 

[calvin0325]

Have been on the end of that one also....oh well I got a caliper on the way to me, I just hate having to go change it in the damn cold.....

FWIW - I used to respect RB as an OEM quality option for brake parts. Then they ****** me around with some front rotors well inside the advertised warranty period.
I replaced them with some Advance Auto Wearever's (a wagner rotor, I think) and had the exact same problem. Advance replaced them, no questions asked. The replacements have been great for 15k.

I'll be avoiding RB whenever possible from now on.

Last time I had front rotor problems I just went to a Midas and had them put in a lifetime set, the cheapest that qualified. Warped out in 4 months. Went back, they put in a new set at no cost, and that is now 3-4 years ago with zero problems with the front rotors since.
