Anyone hear or do a big brake 92.5 to 94 calipers swap to the rear of a 1g?

A Custom bracket and the loss of the parking brake sucks but it would seem to be a straight forward idea for those of us looking for bigger rear brakes to match the fronts and keep the bias closer to stock. The parts are available at stores still unlike the rear AWD calipers.
 
Do the Outlander front brakes bolt up?
Do the big DSM / Early ‘95 AWD rears bolt up?

These are the upgrades I had on my car w/ ABS MC / booster (stock car was ABS) and a non-ABS proportioning valve and man did this set up feel really good.

If this stuff bolts up to your car message me as I currently have the setup for sale due to parting out my car.
 
2g rears don't bolt onto a 1g rear.

I've got 92.5 - 94 big brake fronts on the car, doing 1g 3000gt front swap with 3g master cylinder. But the 1g rears are not only hard to get nowadays rebuilt from stores but they're single piston so I'm curious if anyone has an idea on the big brakes fronts, on the rear. This would seem to be possible and an easy bracket and I might have to be the first and come back.
 
You're talking about putting front, 2 piston calipers in the rear? Why? That's going to screw the bias up massively and more than likely cause rear lockup well before you'd want it. If anything I'd rather have more front bias.

Aside from not seeing the necessity, it's not going to be a simple undertaking, and not having an ebrake is something I personally have been through, and it sucks.
 
Fronts will be 3kgt 4 piston calipers, this alone screws up the bias if the rears are stock. Adding the small 2 piston calipers and 10.8 rotor to the rear would be a balance and increase 60-0 stopping on a current 560hp car (my daily 28psi is 56lbs of air). With the 2.2L coming and better heads etc it'll easily be a 650hp car and I'll wanna stop better.

Not having the e brake does concern me, I'm an auto but have needed it twice in the 140k miles I've put on this car. There's ways to do this if you're creative.
 
im going with a wilwood setup on my car. getting rid of the rotating mass of the stock rotors as well as the huge increase in braking performance. all together the wilwoods drop about 45lbs off the car.

I saw that in your build. What happens to the ebrakes?
 
I will just add some info as I have successfully swapped evo rear calipers and I will say that it does not lock up at all. I also don't have abs. Granted I don't have crazy pads, will have hp+ installed soon. I also have fully functioning parking brake with completely functioning backing plates. I will also say that it was not cheap to do it. Pictures Are in my build thread. If you guys have any questions, just ask.

deleted LOL. mines an auto car so really dont have a need for it. the car now doesnt have any e-brake components on it except the calipers.

Oh yeah :banghead: :p

OP. Inspect the e brake cables and use the better of the two. Also check the brake and fuel lines at the d/s rear by the wheel well and in front of the tank. They tend to rust and leak.
 
3000gt trailing arm swap is the only alternative to keepin the hand brake. They'll physical bolt up but there are three issues that need to be addressed. The ball joints on the 3/S are larger, the active toe sleeve is 2mm larger and the rear shock mounting stud is both larger and 2" lower than stock.

If you are good at fab work, these are all trivial/easy fixes.
 
Years ago I installed PBR/ 96Corvette caliper and rotors to my 92 Talon. still have an E brake. Rotors are 12" vented. If you have the money 2 piece rotors are available.

Pagosa, any pics of your rear brakes?
 
yes on my profile page . I think I did a write up on it years ago. I gave the plans to RTM and Jay racing year ago

While I don’t have any super detailed images of @pagosa dsm rear brake setup (found in the pics under his profile), here is a shot of the rear vette PBR calipers on his 1g. I’m pretty sure he had to make an adapter bracket and machine the vette rear rotors to make the setup work.

Next big question, any ideas with rear caliper upgrade to fit inside 15" wheels. In Australia I run a GVR4 in Gravel rallies and am looking at using Saab front rotor or GVR4 front rotor. I have an inline bias adjuster. Cheers Ross

ive got a buddy that does rear brake upgrades for the dsm to fit a 15" wheel. most commonly used for drag applications but he might be able to come up with something that would suit your needs. usses wilwood parts and some billet brackets. @antilag_200
 
The big brake fronts at 10.8" should fit under a 15" wheel.

I'll find out soon if the big brakes and a custom bracket are practical or just running FWD calipers using the AWD bracket tweaked for the e cable is easier.

I'm a tool dealer. There is a Cobra in a shop I call on. It has a PBR caliper on front and rear with 15" rims. Will take pictures and measurements next week
