master cylinder choice (1 Viewer)

[lurch]

I noticed on the tech links when doing the front disc conversion with mini truck parts that you could use the mini truck's master cylinder for disc/drum. On my fj40 I have JT Outfitter's front disc conversion using Monte Carlo parts (the same parts used in rear conversions.) Would using the mini's master cylinder make sense or would something else be a better choice?

I think the surface area of the puck in the Toyota and chevy calipers is roughly the same maybe less on the chevy part.

So here is the original thread...

I bought a booster and MC from a '95 pickup last night for $25. Even better...the SOB bolted right up! The booster is much larger and the MC is a larger diameter.
I'm hoping this will shed some light. I'm thinking that I have two problems- 1. the MC needs to have more volume and 2. I still a problem with the rear lines. Maybe a blockage, I have been getting particles in the fluid when bleeding the brakes.

I think you are fine. The 95 MC will have a 1" bore (if off a 4wd). That is larger than the early mini's which was 13/16". You will probably not have much pedal travel. The larger booster is a bonus.

Your right Jon! It worked problem solved What a difference, not only can I stop but the brakes are now touchy. That extra bit of volume on the MC makes all the difference and the extra boost really helps. No more acting like Fred Flintstone.
