i have the 8 pot 330mm on the frt
The drivers side caliper gets very hot with little use,
The passenger one is fine,
Changed the seals still no good
Any ideas please and has anyone else had the same problem
Cheers

Are they shimmed up properly, if not one side may be binding.

These calipers are designed to use a 17mm (new) thick pad, the actual pad shape is availabe in 17mm and 18mm (and 25mm for that matter) thickness from several manufacturers (Ferodo and Pagid for a start), could you have one or more 18mm pads.

Pull the pads out and measure them and the caliper gaps each side of the disc, this should spread some light on the problem.

air or water in the fluid??

evonorth

Yes tryed 3 diff pads now, 17mm all new,
Even taken 2mm off each pad still no good,
Bled the system
I am trying to buy a new caliper but told you can only buy a disc seperate
Not very happy with this now,
can't believe may have to go back to the brembo set up after buying this kit

Is there equal spacing on either side of the disc, there is spacer washers in the kit to centre the caliper so the pads have equal contact on the disc. I never had to use them but the washers were supplied so theres a chance some cars need them

Maybe something is bent in the caliper mount. Something must be rubbing to generate the heat. Have you tried just putting it all together and rotating the wheel by hand and listening for rubbing. Only other thing I can suggest is that you discuss with bren@apex who markets this kit.

I/We have tryed everything
Will have to phone him for answers

Knackered wheel bearing ?

Is it tight when you rotate by hand.

evonorth

thanks for some suggestions,
Will try rotating by hand

evonorth

Tryed rotating the 2 frt alloys
The drivers side which has the problem is alot tighter to turn,
Might it be the abs unit is knackered

D1CCY

Can't see the ABS having anything to do with it. Something is binding, is it ok with pads removed, are the pads hard to get in/out, are the pistons hard to push back ? seals binding. It must be there to be discovered if you can feel the tightness.

evonorth

pads are as norm to remove,
pistons need a clamp to go back in,
the car will not roll on any gradient,
seals have been changed,

D1CCY

Sounds like one or more pistons sticking. All I can suggest is that you have them overhauled by ksport.

Whip out the pistons, and give them a vicious polishing....

Thanks for the comments
Could a warp disc do this as when spinning the wheel its get easier than stiffer

D1CCY

Don't think so. A warped disc would knock the pads back, possibly give you a long pedal and wobbles on braking but won't cause binding.

SORTED
All sorted ,
Turned out to be the pad/caliper bolts have 2 sleeves
These are very weak and to short
Thus the caliper was bending and causing the pads to hit the disc,
This is a very cheap part,
I had to put a much thicker and longer sleeve in
The brakes are spot on now
