OK...so I've been digging for brake info...and there is enough to make your head spin...and yet there are huge gaps in info...so this is what I have, and correct me where I'm wrong. My goal is to determine what I need to upgrademy front brakes being as I have the 4 cylinder brakes.
1- I see lots of references to V6 brakes..what I've noticed I'm my research is this: in 88 the calipers changed and are the same for all remaining years of Gen 1 regardless of engine OR wheelbase.
2- Caliper brackets however are different between 4cyl and V6, and the reason is to accommodate slightly beefier rotors on V6.
Question: is the mount point for the bracket on the steering knuckle/spindle still the same between both engine variations? IE are the brackets mountable interchangeably?
3- V6 models use a larger booster and master cylinder than 4cyl
Question: will the V6 booster bolt in a 4cyl with modification?
4- I cannot find a listing for 87 and under pre-V6 caliper brackets, the calipers are different, and the rotors are different (part number-wise anyhow)
Question: do any of the later model Gen parts swap over to the early models (87 and older)?
Question 2- Has ANYBODY swapped Gen two brakes to an early Gen 1?
Edit: dug through FSM and discover than early (87 and prior) Gen 1 doesn't have a caliper bracket. The caliper bolts directly to the steering knuckle/spindle...
Question: can later model Gen 1 spindles be swapped into early models?
Fast forward to #4, question 2. Forget about everything else. I have 94 brakes on the front of my 89. 96 on my 87. They are all V-6 in the later models. If you can get the assy from a JY, you want;
1. The metal lines and rubber hose allthe way to the caliper.
2. The caliper
3. the rotor
4. the backing plate
Get it all apart, take off your backing plate. Bolt the later model one on. Put the caliper on.You'll see that the caliper hits the backing plate. The bolt pattern is the same, but the backing plate is clocked differently and hits the calipre. Clearance the backing plate. Unbolt your old rotor and bolt the new, bigger, beefier rotor on. Re-assemble everything. Bleed brakes, stop on a dime and give change. I typed all this in one breath- you gotta love Monster!
