Sticky caliper
Discussion
Front right caliper on my 95 Chim seems to be getting sticky, especially when the brakes have been warmed up a bit. The left was changed before I bought the car and I guesss that I really should change the right one. Question is, how much? I've found prices from 235 (on the internet from a PH link) upto 285 + vat (from David Hendry) plus fitting. Has anyone got any suggestions please?
I've got a pair of calipers in my garage if you're interested. Free to a good home. Basically when I upgraded my Chimaera to 4 pot calipers I took the std ones off (which were working fine at the time) and shoved everything into a cardboard box - EBC discs, 2 calipers, pads etc.
Email me if you're interested.
Otherwise, it is a standard Ford Escort/Sierra caliper. TVR used several different types so best take it off and compare at a motorists discount. I'd be surprised if it was more than £70-80 though. Those main dealer prices sound a little steep to me.

Thanks for that Trefor. I went to a local shop this morning and the caliper is the same as a Sierra 2.0 16v non-abs. Cost - £45 !! Bought the requisite 7 mm tool, got home, tried to dismantle the brake and found that the inner pad was stuck fast in the carrier. Removed the caliper, got it apart with help from a hammer, cleaned it all up, greased (as per the bible) and it no longer sticks! A straight forward job when you have the right tools!
Stupid question time. Trefor kindly gave me the brake parts.I replaced the sticky offside caliper, both discs and all pads. I noticed that the nearside caliper looks different to the offside but decided that as it is new and one of the sliders was stuck fast, thatI would leave it alone. Problem.... offside caliper (replaced) is still sticking after hardish braking but car also pulls to the left!! The wheel then gets very hot!! Its not the bearings - I did 100 miles down the M4, stopped at Reading (without a lot of braking!) and the wheel was still very cool. Am I being stupid or should both calipers be identical?
Left and right calipers should be identical, and if the new ones aren't identical to the ones they're replacing its not safe to assume they will bolt straight on.
Before you go replacing calipers I'd start by checking that the pads move freely in the caliper and the sliders are clean, lightly greased and not damaged.

Not quite sure 'when' you were comparing calipers. Were the calipers identical before you stuck my old one on? Or is mine different? Yes they should be the same type of caliper/size of caliper (I can't recall if there is a left/right for them though). From what you're saying it sounds like you've got a newish caliper on the nearside? Could it be that this is the wrong part and was on the car before you got it?
If the side that you replaced still appears to be sticking, are you sure this is what is happening? Have you tried replacing both calipers? Maybe the symptoms are masking the actual problem?
Maybe it is a master cylinder problem. Not expensive, just a sod to get at.

Did all of that first! The caliper from Trefor was the same as the one that I took off and when it went on, it was moving very freely. It was the other one (that I couldn't get off) that was replaced by the dealer before I collected the car for what looks like a different shape. I am wondering if, because the two that are on the car aren't identical, it's this causing the sticking problem. It's the same fault with two different (but identical) calipers fitted to the same wheel.
Trefor, the calipers that you gave me were the same as the one on the sticking (offside) wheel. The one fitted to the nearside by the dealer is a different shape, and a different bleed nipple.
I was wondering if that (newer)one might act more freely when the pedal is pushed giving the pull to the left, and stops the other one releasing its pressure back to the system - hence it sticks. When I put yours on the offside, it was moving very smoothly. I took the car out for a run and worked the brakes fairly hard - no sticking but a bit of a pull left. On the M4, traffic comes to a stop, I brake from the legal speed limit!? and the offside caliper sticks. Lots of squeaking and, shortly after, me on the hard shoulder with one hot wheel! It does slowly release, but not fully. When everything has cooled down, its free again!

Had the same problem with my griff, striped the caliper down twice cleaned and greased etc and it still stuck, turned out to be a rotten brake pipe. The inner wall had colapsed and once replaced the sticking caliper was cured, worth checking.

Definite a possibility, esp. as the sticking caliper appears to release eventually by itself.
