I am having a problem for the second time with my front passenger side caliper locking up. The first time this happened, I took her to the doc. and he swapped it out with a used one for a fraction of the price. Could it be this caliper is faulting now? It has been about 10,000 mi since I changed it last time. I don't know how many miles were on this used caliper when it was installed back when, but I am wondering now if it is some other problem with the braking system that may be causing this problem as it is the same wheel that had the trouble originally...
I'm guessing its just a good ol' case of my crap luck.
Any info, or help would be greatly appreciated, as always.
Anyone know of a place to buy XJR calipers for these 99's used or rebuilt??

 

Just did a brake job on my 99 xjr with no problems...114k miles. Never had an issue.

 

What do you mean by the caliper locking up? As to where to buy some, I would start with eBay or one of the forum sponsors.

 

The caliper seized up on the rotor and won't release. I'm wondering if there is a way to free it up, or repair it short of having to change it, yet again. I actually made a $20 offer on a used one on ebay and got it. The seller has it marked as fully functioning without any problems, so, it looks like I'll be changing it out. Again.
I will be looking into a fluid flush as wll, as I'm seeing that dirty fluid may be the culprit behind a repeat offender.

 

My left front caliber was doing the same thing. It had corrision on the piston causing it to not relax enough. Brake dust everywhere. I replaced both front with remanufactured centrics. I also replaced the pads with centric ceramic pads. Works great and virtually no dust. For the cost you might be better off with a reman as opposed to used. I found unloaded centrics for your car for less than $40

 

Does anyone know if the 99 XJ8 and XJR's use the same caliper?
The seller I'm dealing with is parting out a 99 XJ8 VDP.
I have the 99 XJR.
Thanks.
