Under Dash Brake Booster Setup? Would It Fit In Our 5's?

The booster and MC are 90 degrees to the pedal. I was looking for a way to add a booster to my underfloor setup and stumbled across this. They also make a dual pedal with hydraulic clutch.

Discuss.

Pedal arm looks pretty long. I'd get the dimensions from the mfr and measure before I though much about it.

The junkyard swinging pedals have been installed in quite a few Jeeps. site:earlycj5.com swinging pedals - Bing If you have specific questions, I expect the owners of Jeeps with this conversion will be happy to discuss.

 

I considered going that route with my 3A due to my fuel injection system being in the way of where a master cylinder and booster would go, but it just isn't practical. I'm going with a completely different setup. There's no way to fill/check the pot without making a removable access panel in the cowl, or removing the dash every time. Plus, I'm not sure it would even fit under the dash. Maybe it would in a 5, but my 3A's dimensions weren't looking good.

Unless you're obsessed with retaining a clean, stock-looking engine bay, the trouble just isn't worth it IMO.

 

Thanks for the input. Figured there were reasons I've never seen these on anybody's Jeep.

I'm looking for a way to easily get a brake booster on my Jeep. I'm ready to swap out my front axle for a Dana 30 with discs, seems like an ideal time to do a little more work and get a booster in there. I feel like the swinging pedal conversion is a bit more than I want to do at this point, mostly feel like the hydraulic clutch is the big hurdle with the swinging pedals, maybe I'm envisioning more work than it really is. I'm not unhappy with my thru floor pedals and I'm not motivated to have a hydraulic clutch. I can fab brackets and mounts easily, is there a common brake booster mod that works with the existing pedals? I see lot's of underfloor setups for the hotrod guys but they typically have the brake pedal as part of the system and don't look compatible.

If I had one good photo of an underfloor booster/MC setup with the existing pedals I would be off and running. Can't seem to find that photo.

 

I am using a Cherokee booster and M/C. I kept the thru the floor clutch pedal but I am using the Cherokee brake pedal set up. I installed a D30 earlier this year with discs and the brakes work great! The conversion was not super complicated, the hardest part was making the bracket for the pedal.
I have pics somewhere if interested.

 

Yes very interested in pics. I have considered going to a single swing pedal but am curious how it looks inside and if it feels funky to have one swinging and one thru floor. Sort of why I was looking at the under dash booster with single swing pedal.

 

I'll dig them up. I kept the clutch through the floor because I am running the AA chain set up and really like it. The brake pedal is still on the right side of the steering column.

 

I run standard clutch/swinging brake on my 3B. I never noticed an issue with them feeling different since the brake pedal travel is so little.

I'm not sharing pics though. It's too Bubba'd.

 

I have front disks and rear 10" drums on my jeep and i dont think a power booster is necessary.

 

Can't find the pics but will take a few more

 

I have an XJ PS set up in my 47 and that has a much harder under the dash area, but it fit. Just enough room on the exterior firewall to put the Wilwood hydraulic clutch master. Now I have PS., PB and hydraulic clutch. With Dana 30 and 12 inch disc's.

 

Looks smaller then my brake booster. I did have to reinforce the firewall with extra metal plate. (Firewall will flex.) This booster is from a 84 S-10 truck and the disk/disk Master is from a 2000 S-10. My swinging pedals are from a 1999 Nissan Sentra.

I would do a dual circuit master with disc conversion up front and 11" drums in the rear. Those that have this setup are happy with the braking performance. If you feel more braking is needed, then fab a booster in the system. I'm with you on the thru the floor pedals, I'm keeping them as long as I can.

 

Going with a hydroboost setup might be an option if you dont have much firewall space and you really want power brakes and hanging pedals. I think someone here was going to try one with the frame mounted pedals but i dont remember who it was or if they ever got it to work.

 

This setup on a 6V Gen/HyLo pump would be slick.

 

Here are a few pics. Disregard the rats nest of wires. Hard to tell but I made the bar that goes across the steering column for the brake pedal. I know it looks high but I am used to it now. When we were on the Rubicon last year I was not getting full pedal and the brakes would disappear in precarious situations. Steep drop offs or climbs. Really sucks to not have brakes at the top of a climb or when trying to drop off a big rock ! Anyway Jonah and Tom figured out the pedal was hitting the floor prior to full travel. When I got back I removed the cross bar and bent it just a touch and they work great now.
The primer brown is the plate I made to mount the booster M/C to. I originally used 2-1/8" plates but there was a lot of flex. I upgraded the one on the firewall to 3/16" and kept the 1/8" on the inside.
Sorry for the sideways pics, I fixed them all before I posted not sure what happened.
