I have a 90 Bronco II and im looking to put bigger brakes on the front and convert the rear to disc. If anybody has any ideas what car I can get the parts from that will bolt on, please let me know.

Thanx,

 

I would have to check the 1990 B2 I am scrapping, but, I think the Dana 35 in it has the larger Dana 35 brakes already on it.

About the closest to a bolt on for the rear would be to swap in a later model 8.8 with disc brakes from an Explorer and put the springs on top of the axle.

 

The 28 and 35 are pretty close. I'm pretty sure that the calipers and pads are the same or very close. There was a brake line change around 86 I think. You could do this: New Page 0 That would give ya 1/2 ton front dana 44 brakes but would change your wheel bolt pattern to 5 on 5.5. I don't know if anyone makes disc brakes for the rear 7.5. Seems I saw some 7.5 stuff in the Speedway catalog. You might check with them or some of the Mustang specialty places. You could swap in a rear Explorer 8.8 with disc brakes if ya'd like to up grade. Or maybe there is a full width out of a F-150 if you want to switch to 5 on 5.5 wheels. I don't know for sure on the last. I have read that the Explorer rear 8.8 axles are large enough to be drill for the 5 on 5.5 pattern. I have not done it though. Might be it can be done on drum. I have never work on the rear disc stuff.

Good luck.

 

Thanx, im open to any direction. The B2 is used for offroad trail racing only. I was planning on going straight axle, but keeping to the width of stock B2

 

The Early Bronco (71-77) is close to the same width. I have had a few of them over the years. My son still has a 74. You can get parts to upgrade a drum brakes on the Early Bronco axles to disc. The Early Bronco used a small shaft 44 and a 28 spline rear 9". Jeff's Bronco Graveyard used to have good prices on that stuff(I haven't bought stuff in a while). My son up graded the front 44 with disc brakes and larger shafts. He is still running the 28 spline 9" rear. He used a master cylinder for NON power assist disc brakes out of a Ford Van (3/4 ton maybe). The 302 is a carb motor so he wanted good brakes all the time. Many of the parts for the EB disc brake conversion are the same as the ones I used for putting 44 outers on my Dana 35 TTB.

But a straight axle conversion is not a "bolt on" deal. The 44 outers on the 35 TTB is very close to bolt on. Just need to drill and tap 8 new holes (4 on each side) and I used a cut off disk on a 7" grinder to cut the "ears" off of the 35 TTB knuckles.

 

SSBC sells a disc brake conversion for the 7.5. It's only about $860.00.

I thought I read somewhere that someone modified there 7.5 to accept 7.5 discs from a later model Mustang or Ranger. I never have heard of anyone else doing that though so maybe I am wrong.

I've also heard that you can modify cobra stuff to fit on the 7.5.

But in any case, if it was me, I would just swap in a 95 or newer 8.8 from an Explorer. You'd have to shorten the driveshaft, put the spring perches on top of the axles and relocate the shock mounts. But I think it would be worth it for rear disc and stronger axles.

 

I happen to be looking in the advertisments in the back of the Nov. 08 issue of Four Wheeler and seen an ad about disk brake conversions.Top of the list is Ford truck Bronco and Ranger. Here is the site check it out see what you guys think. " Ranger, Bronco II, Mustang "

 

Do like us jeep guys do in our YJ wranglers, swap in an explorer 8.8. It's stronger, alot of them are 4:10 gears, some are lsd, they have the big bearings and good axles and disc brakes. Just takes some minor fab work on spring perches and all, not hard. There's alot of 8.8's running around in wranglers and it's catching on to the bronco II crowd as well.
