Hi I was looking on Brembo's website for technical details on brakes as I am looking on upgrading the brakes of my 1.8. I found the diagrams really useful as I know what I have to look for, and thought it could be useful for those willing to go the aftermarket route on big brake conversions.    the on line catalog is here Additionally I need to find the piston diameters of Master cylinders and Calipers too, in order to work out the force ratio applied by the master cylinder on various calipers. If any of you has any details please post here. |

I love offset.

Excellent stuff, thanks for posting this. Now pinned. Will be handy for the brake conversions alright, especially the offset and depth figures - if anybody was going down the two-piece rotor route. |

2.3 and 2.5-16v are the same are they not (just to be sure) |

Some new data came my way. Caliper Piston diameters: 1.8 - 2.0 solid disk, piston is : 53.9 mm 2.6 vented disc : 54 mm 2.3 - 2.5 16V : 54 mm EVO calipers : large piston 42 mm small 38 mm From the above details it is obvious that brake upgrade from solid disk to vented(2.3 - 2.5 calipers) does not require bigger than stock master cylinder as the displaced volume of brake fluid is almost the same as stock. But this is OK as long as the rear brake calipers remain stock From those data braking performance between 1.8 - 2.6 cars should be equal. The only difference will come at enthusiastic driving where vented discs will dissipate heat faster and maintain better operating conditions. Edited by alogaparaloga, Fri Feb 20, 2009 10:42 pm.

This is good, but to really noticeably increase braking torque you would be advised to increase the size of the rotors and cnc a spacer that sites the stock calliper further radially from the hub. +20mm makes a worthwhile difference. Only problem is that larger wheels need to be fitted. regards nathan |
