EB Power Disk Brakes - Pirate4x4.Com : 4x4 and Off-Road Forum

Did a search but ??? Have Dodge knuckles, disks, calipers, and spindles to convert my 74 Bronco to disks. Would like to go power while I'm at it but what booster and MC? Any help would be appreciated.

If your running an auto look into a hydroboost conversion. It's a tight, almost impossible, fit with the clutch there. But running an auto you can move the booster outboard. I just got the rig running this weekend and with 4 wheel disc brake's that's 100% better than the vacuum boost. I got the hydroboost unit, lines Saginaw pump and all from a wrecking yard Lincoln for about $40. The pump bracket needed modified but wasn't a big deal.

Thanks for the info, I run a Hydroboost on my Jeep, and it's got crazy strong brakes. The Bronco has a NP435 so linkage is a little tight. What MC would I use if I left it manual brakes? The rigs still got drums in the back.

I'm running Blazer discs up front with the F250 Camper special Master cylinder. It has a 1 1/8" bore if I remember correctly.

WOW...this group has really gotten tame...just a few short weeks ago, this poor guy would have been flamed into submission for not searching...There are hundreds of pages out there on dozens on eb disc brake set-ups.

That being said why not just go get a remaned 77 eb m/c for about $25 from napa. 77 came with disc/drum as standard equipment. As for the brakes, most use early 70's backing plate, spindle/caliper with the bronco rotor/hub for a 76=79. Those cost $24.99-$30.99 at Autozone new. Others get the caliper bracket from an f-150/78/79 bronco and use the appropriate caliper.

The only problem with running a manual disc brake m/c is, the ports come out on the passenger side of the m/c, putting them real close to the throttle linkage. Tricky but, doable. Just got to make some fancy bends. Mine's been working fine for 16 years

Thanks for the input on the M/C, i'll be tear'n into her this weekend.

Don't forget to change your proportioning valve to a disc/drum version or, run the front brakes right off the m/c and the rears trough an adjustable one. Works great once you get it adjusted how you want it. Good wheelin'.......Hans
