bogan393 Member 77 Member For: 18y 8m 2d Posted 02/12/06 08:45 AM Share Posted 02/12/06 08:45 AM (edited) Hey, I've just found a nice set of 330mm rotors with 8 piston calipers that will be going onto my t in the next month or so, and I was wondering the the standard 2 pison front brakes can be easily fitted to the rear for a bit of extra stopping power? Any help would be great. Edited 02/12/06 08:46 AM by bogan393 Link to comment Share on other sites More sharing options...

bushuteF6 Member 10 Member For: 18y 3m Posted 02/12/06 10:37 AM Share Posted 02/12/06 10:37 AM As BAturb said - you'll need to balance front and rear. Your master cylinder will also have been designed to provide a certain amount of pressure by volume for the current setup. Coming from a full rebuild on a Lotus race car I can provide the following tips:1. Master cyl valving/bore will provide a set volume "push" for a given pedal travel.2. Braking force is directly depenedent cylinder bore/pistion diameter. Bigger pistons will need more brake fluid volume to push them the same distance.3. More pistons does not necessarily equate to more brake force.4. Calculate your combined pistion area. If its more than standard your brake pedal will travel further. This is NOT a bad thing it just means you have to push further (but less effort) to compress the brake fluid. Unless of course your master cyl is way below the volume reqd for the new pistion area.5. Calculate your current front to rear ratio I.e. pistion area front / pistion area rear. Do the same for the new setup and if they are WAY different you'll need a bias valve. E.g. std = 70% / 30% and new = 55% / 45% then you'll need a bias.As an aside, always be careful with doing this on ABS systems. Changing front rear bias could have a dramatic effect.Cheers all - this is my first post so apols for the rambling. Link to comment Share on other sites More sharing options...

bogan393 Member 77 Member For: 18y 8m 2d Posted 03/12/06 04:51 AM Author Share Posted 03/12/06 04:51 AM Wel I never thought it was going to be so involved lol, my bugdet doesnt really stretch out to do the rears aswell, especially if I have to buy 4 or 6 pot rears, I might have to put it off for a fair while by the looks of it.

bogan393 Member 77 Member For: 18y 8m 2d Posted 03/12/06 06:41 AM Author Share Posted 03/12/06 06:41 AM So is it deffinately not possible to put these brakes 8 piston brakes on without upgrading the rears? if not what are my other options that arnt too pricey, preferably under $4000, other then the pbrs, I havnt heard good things about that upgrade.
