4200 GT 2004 Brake Calliper Pistons Exact Dimensions.

[paul328]

I have trawled through the forums to get the exact details of the Pistons and dont se any exact details. One post suggests the Piston diameter at the front is 38 and 46 and rear 34 and 30. I have been trying to source some pistons. Does anyone have the exact dimensions of these or a part cross reference? I cant find anything on the Brembo site and the after market companies say they need exact dimensions to compare and supply.

I want to order these before the mechanic strips the callipers in case we need a piston in particular at the front to save downtime on the ramps.

Any help appreciated.

I know I’ve been through this in the past but not to the extent of piston height or o-ring dims etc…

I'd give AP racing a call , they know all the specs for Brembo brakes used by Maserati

If I recall correctly, the front pistons are 32mm high, which only matches one type of Brembo piston. @Gp79 rebuilt a set so might have more info / spare pistons to measure.
