OK, here's the scoop,
I'm about ready to get the pinion brake hooked up, but i haven't decided what to do about the master cylinder. I have to use the rear side of the MS because the pinion brake will be on the rear axle, so i switched the big reservoir to the rear, and little to front.

If i only fill the rear with fluid, the fluid should push on the front piston instead of the caliper, right?

So - Should i buy a blocked fitting that stops the flow to the front, and put it in the t-connector mounted to the pass. frame rail --

Or - Is there another way to stop the front piston from moving?

What is that little 10mm bolt bolt that goes into the side of the MS? Can I tighten that to stop the front piston?


Any info Appreciated...

I think hydo force is the bet way to stop that front piston. maybee run a short 3/16" line to a cap or plug. its not anymore force than that circuit dosent see already.

how big is the cailper?
teeing both lines togeather would give you more volume?

but I say, fill the front and cap it <IMG SRC="smilies/beer.gif" border="0">

filling the front is the easiest thing to do. but what if it leaks or breaks, then i will have no brakes at all.
The pinion brake is standard chevy 1/2 ton rotor and caliper.

I don't want to T them together, as i may convert to 4wheel discs in the future, and i will need that front brake line back again.

does anyone know what that stupid bolt is for???

That bolt is a stop, which keeps the front piston from coming back to far in the cylinder.When doing a rebuild, you must remove that bolt in order to take the front piston out.

I dont know if this will help, but the president of TLCA (Dave) is useing a master cylendar out of a Toyota celics. it is a single cup and has the same mounting pattern as the fj40. he picked it up at a bone yard for about 30 bucks.
