    What is the master cylinder upgrade for iX booster?

    My brakes stick on the more they're used, I think the master cylinder is not releasing. I have an m50 swap using an ix booster and e30 m3 brakes. A bigger master would firm up the brake pedal anyway, but what is close to 25 mm and fits the offset studs of the ix booster?

      OK after a bit more looking around online, seems the E34 M5 part # interchanges with all e34 and e32 with the vacuum assisted brakes. Anyone know the internal diameter of it?

        OK, answered my own question. For posterity, the 5/7 series master is listed as 25.4mm here:



        "Diameter 1 [mm]: 25,4
        Manufacturer Restriction: TRW
        Number of ports: 2
        Thread Measurement 1: 2xM10x1
        from construction year: 04/1988"

        Whereas the e30 ix master is listed as 22.22



        "Supplementary Article/Supplementary Info 2: without brake fluid container
        Bore Ø [mm]: 22,22
        to construction year: 03/1993"
