MG MGB GT V8 Factory Originals Technical - Brake caliper piston specs

Anyone have details of piston specs for common uprates ie SD1 etc
Paul Wiley

Paul,

SD 1 single pot callipers are not first choice for a V8 conversion. The pistons used on the factory V8's share the same part no. with the 4 cyl. B and are intercargeable. The V8 callipers inner halfs have a differnt offset due to the thicker V8 discs.
The part no. of this one half is identical to those used on Triumph 2000 and 2500 passenger cars of this period. The dimension of the pistons are the same as those used on all MGB's, including the V8.
May be you should contact Dave Vale (V8 Conversion Centre) and ask him for some hints.

Before you go for an upgrade, have your brake servo checked, as these do not work O.K. sometimes, giving you the feeling of insufficiant brakes too.

Thanks for reply but just trying to work out brake balance with SD1 4 pots, had a nice chart from someone.
I use Wilwoods myself.

Paul,
I produced a simple table some time ago, with piston sizes for the various caliper options. Happy to forward it...just send me an email.
