Dodger Posted September 21 Report Posted September 21 Has anyone successfully installed 4 wheel disk brakes and new master cylinder? If so, what brand did you use? Please provide link if you still have one. What modifications were made as there isn't any room for the new master cylinder boosters around the starter. Thank You, Dodger Quote
bkahler Posted September 21 Report Posted September 21 I have front (Rusty Hope) and rear (Jeep Wrangler) disc brakes on my B3 and I used a Dorman MC. Made a custom mounting plate/adaptor and it works just fine. Quote
Robert Harrison Posted September 21 Report Posted September 21 I've seen some conversion kits for front brakes but I have not followed it as I am interested in restorations. 90% of your stopping power is from the front and that end would be an easy conversion to do. I think I would go that way. Also preserves the value of the truck as someone could still convert it back easily I suppose. Try calling DCM Classics they have parts for your truck and might have a suggestion. Bob Harrison Quote
Dodger Posted September 21 Author Report Posted September 21 Copy ... Front conversion isn't an issue. I was hoping there was a kit for all wheel conversion. Quote
Dodger Posted September 21 Author Report Posted September 21 BKahler, was your adapter for the mater cylinder or the rear disk conversion ? Quote
bkahler Posted September 21 Report Posted September 21 There is no single source kit for disc brakes on the Pilothouse trucks. As for the rear axle, I doubt you will be able to find any direct conversion of the original Mopar rear differential assembly. I only made the rear conversion because my original ring gear was cracked in about 10 places. Sourcing an original type replacement was more effort that it would have been worth. The Jeep Wrangler conversion wasn't all that difficult and I was able to find a 3.73 that matched what was originally in my truck. The bonus is having a truck that stops on a dime with little effort 1 Quote

The adapter was to adapt the MC to the bell housing. It's nothing more than a 1/2" (or thicker) aluminum plate with the appropriate bolt patterns for the bell housing and the MC. I may have a copy of it laying around here somewhere. Quote
bkahler Posted September 21 Report Posted September 21 Here's a picture of the MC installed with the adaptor plate and a picture of the plate I used as a pattern. The adaptor itself is 1/2" thick aluminum plate. The plate can't be any thicker as there would be a clearance issue. When bolted in place the backside of the MC is about 3/16" from the steering gearbox. 2 Quote
Dodger Posted September 21 Author Report Posted September 21 Yes !!! I like your fab work. I think this is the direction I'm heading. I didn't see the break relay switch on that MC or the pics on the web site you sent. Is it on the other side of the MC? Quote
bkahler Posted September 21 Report Posted September 21 The brake switch is installed in the brake line T under the drivers side frame rail. There originally was a T there but I replaced it with appropriate sized openings for the new brake lines. Quote
Dodger Posted September 22 Author Report Posted September 22 Appreciate the info. I'm tracking now ... Quote
Dodger Posted September 22 Author Report Posted September 22 Because I've only had my truck for 3 weeks now I'm still not sure what gearing I have in the rear end. I do know that I want to go disk all the way around. Do you remember the parts for the rear disk conversion? Quote

I do know that I want to go disk all the way around. Do you remember the parts for the rear disk conversion? The choice of parts depends on which donor rear axle you choose to go with. I ended up using a Dana 44HD-A rear axle from a 1997 Jeep Grand Cherokee with 3.73 gearing and disc brakes. It was the first one I found that matched my criteria. Changes involved removing all of the old perch mounting hardware and adding new replacements. For the most part, after getting the new perches set up correctly it was a drop-in replacement. You can read about my rear axle conversion here. 1 Quote
Dodger Posted October 5 Author Report Posted October 5 BKahler, quick question on the new MC. Did you have to modify the brake plunger do to the adapter plate offset? Quote
bkahler Posted October 5 Report Posted October 5 Yes, the plunger needs to be shortened. I probably have a sketch somewhere, I'll see if I can find it. Quote
