FOR SALE: Refurbed Rear Calipers

[zx_volcane]

Ooohhh tempting...

Rekon the 2mm would make a terrible difference?

Unfortunately they will i think

Just to say, these callipers can be a bit of a bastard to rebuild (mostly the handbrake mech) but its well worth doing even if you think that yours feel fine. Believe me you will notice the difference on refurbed callipers. Well worth the price these considering the hard parts done for you

Sorry bit of a thread hijack but what are the 32mm fitted to compared to the 30mm 1s?

They were an absolute arse to do, I spent a stupid amount of time swearing at them, utter pig - and I made myself a tool for compressing the concentric washers and everything.

gti-6 had 32mm, others had 30mm - although think a lot of the later 306 ran 32mm as per usual pug parts bin special

I ran these unintentionally as a pair and didn't notice a difference BUT they weren't in the greatest condition before I refurbed them, passed mot brake balance ..etc Lets face it they don't do an awful lot on the back as it is. Not by any means recommending it though.


Right hand is 30mm Left hand is 32mm

Ooohhh tempting...

Rekon the 2mm would make a terrible difference?

lol


yep, its a fair difference in surface area.

---

iirc its 2.8 vs 3.2 cm2 so about 20%.

area of piston contact to pad face is same on each

area of 30mm vs 32mm is approx 700m2 vs 800m2 so about 12.5%

Not sure how this works as we're moving volume of cylinder, only by a fraction though. So you could factor that in too, although say the pistons move by 1mm then its just a factor of x1.


tldr - calipers still for sale
