Hi FSJN,
I've done a good bit of searching on the various forums, parts/restorer webs and Google for these two specific items. There's lots of discussions around them but I've yet to find the definitive answers and a specific part number. Any help would be greatly appreciated.
My build- 1964 Jeep J300 Gladiator 4x4. Previous owners have swapped in a 1979-era Chevy 350, moved the manual 3-speed shift from tree to floor (T90-C transmission) and converted to front-disc brakes (with original Master Cylinder & line distribution, i.e. no proportional valve).
I've pulled both the Clutch and Brake Master Cylinders out for rebuild. But both have serious pitting of the bore sleeves and should be replaced (or relined).
My asks-
1. What "new technology" Clutch Master Cylinder will fit the existing mounting holes and pedal push rod without modifications (i.e. plug&play)? I expect this could be an actual brake MC repurposed as the clutch MC. Someone must have done this on one of their builds/restores by now, you'd think.
2. What "new technology" Brake Master Cylinder with dual-ports will fit the existing mounting holes and pedal push rod without modifications (i.e. plug&play)? A disc-brake conversion/upgrade should have included updating the MC to dual port and adding a proportioning valve to adjust brake engagement between front-disc-to-rear-drums. The J300 came with the valve sitting in the glove box (maybe not the correct install location).
Original Kaiser-Jeep Part Numbers:
932829 - Brake Master Cylinder
925373 - Clutch Master Cylinder
I'll continue my searches and post any successes here for others to benefit from. I'll also post up on the IFSJA.
Thanks for your help!
