power brake conversion options

what parts have you guys used in your power/disc brake conversions? I'll be using the stock disc brakes on the front and drums on the rear of the D'44s that are going to go under the flattie. Trannny will be an auto, so... single pedal setup.

i was thinking about finding a booster/master cyl and brake pedal from an automatic TJ or a cherokee and adapting it to the flattie.

what have you guys tried?

 

To be truthfully honest you don't really need power disk brakes. I have been running my manual ones for about 2 1/2 years now and drive it on the street quite a bit. They will lock up easy if I want them to. Unless you have some other reason I would forgo the booster as its something else to take up space and go wrong. YMMV

 

my engine will be built to well over 300 hp... i figure if i have lots of go power i will want lots of stopping power too. But if you guys think i can get away with it, i'll skip the booster and go with a Wilwood swinging setup.

 

i agree, but brakes is one of those things i dont like to go cheap on

**edit** actually i just priced it on summit's website... the single pedal with the single master is 110$ together. that aint bad!

 

The usual problem with a brake booster on a swinging pedal is room for the booster can. Some alternatives would include a hydroboost (can be junkyard sourced; Astro Van, Cadillac, among others) or a remote booster (master-slave-booster-master-wheels, $$).

 

i'll be retaining the D18 t-case with e-brake for emergency braking situations. it's never let me down

 

The hydro setup would work seen it done.

I passed on power because when you stall you lose the extra and then not much control.
Of course with manule they stay the same

You need to reinforce the fire wall with an extra layer of sheet metal.

the dual master should be a law for all auto's, I wont drive anything without it.
Had to convert my daughter's early mustang.

 

Take a look in street rodder magazine.There are some interesting steering and braking pieces in there including compact boosters.

 

Take a look at this thread, scroll down to username "coas." This guy used a late '90s Mustang hyrdoboost setup that looks like it would fit even a flattie.

Wilwood makes a dual MC. I used it on my setup. Not the one mentioned above. If I were running an automatic, I think I'd want the booster.

Something I haven't seen mentioned yet is the vacuum source. You say you're building the motor which is great, but if going with a big rumpy cam that creates a situation where the motor doesn't produce enough vacuum at idle/off idle to run vacuum items like power boosters. Then you have to get a vacuum reservoir. Non issue as long as you are careful with the cam you choose. Nickmil

 

really good point!!

so if i forego the booster, what do you think of a dual setup like this? http://www.wilwood.com/Products/005-PedalAssemblies/002-FSMP/fsmdmcbp/index.asp

 

My Jeepster has 35's and a 4.3 V6. I have manual brakes, and it's a real pain in situations where the vehicle in front of you stops and you are sitting on a hill having to have both feet on the pedal. You're going for high HP and big tires, I'd say power brakes are a must. I already have the Astro ps pump on my 4.3, and still have the hydroboost from the van. I'm going to put it on this spring hopefully. If you're going to spend money on brakes, might as well go power.

 

Now that you bring it up, would a canister from cruise control work for a reservoir?

 

i was thinking that that one looks kinda small and you would get a lot more stopping power out of a dual setup. am i wrong? :?

 

I'm using a Wilwood dual MC, similar to the one in your post. Same basic size and I'm running 4 wheel discs and it has plenty of capacity to work those.
