12" brake project

[Malibutomi]

Hey guys...im planning to do the big brake project at this winter, just got some questions.

Can i use 92 Buick Roadmaster spindles? Or do i have to get some older ones? Part # 6109R on one and 6120L on the other.

I plan to use UB machine upper control arms, as someone did it on the oldspower forum:
http://www.oldspower.com/vb/showthread.php?t=19243

So the question is, how do you set the suspension after the conversion? I think it wont work with the factory specs any more...will it?

Thanks for the answer

Any thoughts?

Cool 8) Whats the part #s? Someone should make that a sticky or post in tech sect. Will make it easier searchin the boneyards for spindles.

It would be nice if we had a sticky that gives the exact requirements with advantages/disadvantages of the 12 inch brake system. It might take a mod to organize it right or somebodys own experience on the best way to do it. I'm sure this info would be highly desired by many of us on this board.

This list is for the #18021052 and #18016024 spindles
Actually i found this as for 84 caprice with 12" brakes

Does anyone used the UBMachine A-arms for the 1LE brake upgrade?

hi,
i have the same spindles on my camino with Global West upper a-arms and 1LE rotors and fits perferct

and the great bore master cylinder from BMW 750i and brake-booster from BMW with double-membrane :shock:

double brake lines from front to rear, brakes X-cross

I have posted a part number list at least 4 times. I thought it had been made into a sticky before.

Here's the B-body/1LE swap info if someone wants to make it a "sticky".


The 1LE rotors are 12". Any year IROC Camaro or the same years of WS6 Trans AM should get you the right rotors. For upper A-arms and springs I used Global West's stuff.

Here's the parts list I used:

Spindles and calipers are from 12" brake 78-90 full size Caprice, Caddy, Delta 88, and Pontiac. Typically wagon, police or with HD towing package.

Brake calipers, (1)#18-4021, (1)#18-4020

Brake flex hoses, #BH36848

Brake caliper hose bolts, #483-205

Brake pads, # D52 ( I used Performance Friction pads)

Brake rotors, 1LE, #5994

Wheel bearings, 1LE inner, #BR6

Wheel bearings, 1LE outer, #BR3

Bearing seals, 1LE, #19753

Hub grease caps, 1LE, #13977



If you're tearing down the steering too, here's the part #s:

Tie rod, inner, 78 Malibu, #ES2034L

Tie rod, outer, 78 Malibu, #ES2033R

Centerlink, 78 Malibu, #DS909

Idler arm, 78 Malibu, #FA1013

Ball joint, lower, 78 Malibu, #FA3000

The tubular upper A-arms required should have ball joints already installed.
