i know its a pointless thred but on my mark 3 supra that ime trying to sell (if any one is interested:D) the front pads needed changing and i was shocked to find that it had single pot calipers on at the front the Z has double pots at the back lol

 

any way just thought that some one may have been as shocked i me lol its a turbo as well

Z's have single at the back, 2 pot at the front AFAIK

i had mine off last night and it has 2 pistons one at each side i thought that it meant it was double pot i thought they were 4 pot on the front must be my mistake but supra just has one bug piston in the middle and the caliper slides like on me corsa

Naughty Christopher!!! LOL

 

4 pot on the front - 2 pairs of opposing pistons

2 pot on the back - 1 pair of opposing pistons

 

Single pot calipers have one single pison on a sliding bracket...

 

CheerZ,

whoo i wasnt wrong :)

I made a mess of the post LOL

What I meant was the Supra can't have single pots at the front surely? 1 piston?

My mate's S13 has Singles at the front too LOL

Lots of " performance" cars have have single pot calipers all round now. Guess they are cheaper to make than multi pots. The single piston is usually a big sod though. Discs are also much bigger these days since wheels and tyres got bigger.

Its about how hard it can squeeze and how much heat the disc can absorb and dump before the friction goes off that counts.

 

I guess there must be some techy reason why Brembo and the

likes are multi pot kings. Presumably you get a more even and higher pressure distribution of the pad on the disc with multi pot calipers.

 

My experience with 10+ year old cars with multi pot calipers is that they can have seized pistons and as long as only one or two are partially siezed you dont always notice it except that the brakes dont stop you so good. When the discs warp or the car starts pulling then you do something. I rebuilt my Z calipers on the front - 2 pistons each side were sticking! New discs had warped within a year. Anyone saying that Z brakes in good condition are crap for fast road use is talking same. They're not up to hard track use but that is different. If the calipers are in good nick you can push the pistons back with your fingers
