on my 87 bronco, i want to convert over to a rear disc setup....Now i work for a Autoshop in my area and i acquired a rear disc setup from a 96 Exploder that needed a rear...I was curious if the setup off of the exploder would work on the 8.8 in my bronco...if not, what years are compatible?Any aftermarket ideas?

There is a company called TSM that sells a rear disc kit for Broncos
go to www.broncograveyard.com and check it out there.

i think this is really popular with jeepers, but i don't know about broncos. if the rearends are the exact same i'm sure it would work. too bad i don't know shit about exploders.

The rears are not the same.
It wouldnt work.
The rears are smaller side to side which makes it such a great swap for a jeep who wants to avoid the full size axle look.

hes not asking about swapping the whole rearend, just the disk brake assembly off of the Exploder 8,8 if i read it correctly.

I would think it should work,as the axles in both vehicles are Ford 8.8". In the Explorer it is a 31 spline, not sure if that will make a difference or not.

I just thought about something. Does that one have a solid axle in the rear or is that around the time they changed it to the rear IFS? I know on '91-'94 Explorers it was the 8.8" 31 spline axle, but I can't remember when they changed over to rearIFS.

If it is a solid axle it should work, I've also seen other Broncos use the Explorers brakes on them so I guess you could use them and the only difference would be how much extra work it would take.

Guys, guys, I'm not sure that the rear disc will work at all. Is the bolt pattern for the Expy. the same 5 on 5.5" as the full size axle? If not, there is the biggest stumbling block right there.

the bolt pattern on the expy is a 5 on 4.5 pattern...its out of a 98 with a solid axle rear...does that mean it wont work though as far as mounting brackets n nonsense goes?

they changed IRS in 01 or 02. it was very recent.

and yes, i forgot about the 5 on 4.5" thing. thats why all the jeep guys want them from exploders.

How are the rear brakes on the '98 Explorer set up exactly [as far placement of the bearings in relation to the rotors]? The 91-94 Explorers, with just the front disc brakes, had the outer bearings in the rotor itself. Could you just replace the rotors with an apropriate ones [ones that have the correct bolt pattern]?

I realize someone will tell you to go buy the conversion to make it easier, but I think I'm safe in assuming you want to try to use the parts on hand to save some $$$$$.

Hi all, I was doing a search like a good little noob and came across something that has me scratchin my head. In the above posts the disc brake kit listed on jeffs BGY and the TSM kit are referred to as the same kit by beerman? They look different, whats the verdict?

also while I have your attention(s), Do I need the e-brake on my street driven Bronco? I think yes because I was under the impression the PARK in an auto tranny is only a little pin that can sheer?

Thanks to all who reply :rockon

just have a machine shop re-drill the 5 on 5.5 pattern into the rotor/drums (yep they are a combo) .... should enable you to bolt them up to your axles.

the hardware will all bolt up to your 8.8sans calipers....that is as far as i have gotten with my truck. i was going to try stock front rotors but i haven't gotten that far. I figured if the rotor was to big of diam i would modify the bracket to fit my needs. I talked to TSM many times but they want 279 bucks for brackets and rotors. i wouldnt buy anything else from them if ya go that way. Go to you local parts store and buy the gm calipers with e-brake or without, alot cheaper than from tsm.
