Hi All,

Upgrading a braking system obviously consists of calipers, rotors, pads and brake lines in most cases, however is there a need to upgrade master cylinders and boosters ?? I've heard mixed things - I'm just curious =]

Thanks,
Steve

You'd have to ask a brake co or check with a service manual to get atleast the right size as one fitted std with same set up. In some cases it's a matter of removing or replacing brake bias valve [drum to disc]...What do the guys say that you bought the stuff off??

the only time you have to change the master cylinder is when retro fitting brakes to or from another model. Even then you can buy bias kits which can be adjusted to compensate for the difference. Using different calipers will usually cause this problem....The bias kit sets & adjusts how hard & how much work the front or rear brakes are/will be doing...

if you get different size calipers - like two piston instead of one - you may need to get a larger master cylinder because the standard one will not be able to move enough fluid, resulting in a low or no pedal, but this is usually only if the difference is very great. if you upgrade the fronts and not the rears you may need a bias adjuster because your front wheels will be getting a lot more pressure than your rears.
