I have been having a brake gremlin show up every so often between my drivers side front and rear calipers. I haven't seen anything on the front since changing the brake hoses....probably need to do that on the back now. I have flushed the system...turned all four rotors, put on all new pads, re-lubed the glide pins, painted the e-brakes springs and tensioner in rear with nickel anti-seize compound...not sure what else to try. My rear drivers side is driving me crazy. I am to the point of replacement @ only (82K miles?)...Is there a way to check the calipers to see if they're okay...or should I just go ahead and replace? I know, the rotors could be warped, so replacing them too would be in order. I've checked the temps on the rotor that is hanging up and its around 650'F...probably not good. Let me know if you think I should replace them, and if so, any suggestions on where to get the replacements from. Thanks.
You don't say what it is doing other than heating up ?
Sure I did...(from previous post) " I've checked the temps on the rotor that is hanging up and its around 650'F...probably not good. " Not really sure how else I could describe it? Its not making any noise...but you can definately feel the drag....and compared to typical rotor temps of 140-190 for other rotors...650 seems a little high. So my question id (from those who have been where I am now)....do you think it is the caliper, and if so, where did you find your replacement? Thanks
Way too hot except if racing. The seals, grease, brake fluid, and bearings will not hold up to that temperature. If it was wood it would literally be on fire already.
You can buy pressure gauges that you insert between the pistons, but, kind of pricey at about $200.00
I would just replace the calipers, seals, and maybe the bearings and completely flush the whole system, I would think about replacing the hoses on that side again.
The other thing is if you have 4 wheel ABS it might actually be the valve itself.
I have never worked on a 2005 so I can't say if your system is the same on say a Land Rover 3. But, with two calipers on the same side overheating, I would tend to think it was a valving issue with a 4 wheel ABS system. I would fix that and then replace the calipers and hoses.
