independant breaking

I am trying to set up my rig to have independant front and rear brakes for front or rear digs to help in turning until I get my rear steer. I am running pinion breaks on my rockwells and need to know the part #s for the willwood break pedals and master cylinders that would work for my rig or any other companies stuff that would work.

Why not use cutting brakes unless you want to use the two peddle set-up.

i don't want anything breaking, let alone things breaking independantly

you could just learn how to actually calculate brAKE system specifics instead of just asking "tell me part numbers that work."

Or just tell us what size and type of calipers you're already running, what current master cylinder you have, and how that's performing for you.

currently I am not running anything. I am in the build process. This is my first time running pinion brakes and I am concerned about turning my rig with locked rockwells ,49s and a 120" wheel base . I am just asking for input on what others have used. I have seen the willwood dual brake setups being run on the pinion brake setups instead of cutting brakes and was interested in what parts were used for those setups.

Pinion brakes mess with the standard guidelines a little bit since they are applied before the gear reduction, but in general you can still sit down and figure out your caliper piston bore, master cylinder bore, pedal length and pivot ratio, and get an idea of what kind of bore master cylinder you're going to want to use....BUT I think you can kind of get away with a little bit less accuracy because pinion brakes work so damn well no matter what.

I'm assuming you'll be running a twin sticked tcase? I think you've got the right idea going for a dual pedal setup instead of cutting brakes. With only two calipers in the system its just simpler.

I'd search pinion brakes and see what others have done. There are plenty of examples, and I think the calipers you pick to run are going to drastically affect what M/C you want.

Good luck
Paul

We just used one of these "compact" setups from Wilwood...Polyperformance has them, just not on their website yet.

http://www.wilwood.com/PDF/Compact-MC-Brochure.pdf

It was a piece of cake to install as you could do the reservoir remote or on the cylinder with the same kit/same part numer, it's all in the box. Because of the design, it's the exact same bore and throw of their full-size cylinders, yet it was TINY, again, making it a piece of cake to install.

We do split pedals on al of our rigs...make sure you put the rear master as the left pedal...that allows you a safety of going downhill with left foot on the rear, right foot on the front...wathc your tires and if one end starts sliding, lighten up on that pedal...if things start to get hairball, keep your left foot fully planted on the rears and nail the throttle with the right. If you put the front master on the left, I promise, you'll be sorry.

Here are the part numbers we used...we were using 7/8" bore M/C's by the way...on a Jeep with 60 outers, NOT pinion brakes. You may need a different bore for your pinion brakes.

QTY 2 - Pedal Assembly - PN 340-1290
QTY 2 - M/C 7/8" bore with reservoirs - PN 260-10374

Hope this helps!

Hope this helps.
