1LE brakes

Those tubular A-arms up there look real nice. One of the car magazines ran an article a few years ago about putting Camaro 12" disc brake rotors from the 1LE suspension package on our favorite body style. Something about finding a certain year(s) Caprice, and getting the upper A-arm and spindle. The rotor on this car is 12", but has a 5-on-5" bolt circle. If I remember right, the 1LE rotor bolts on the Caprice spindle, and gives the right BC. Anybody know what I'm talking about? :roll:

12"

78-90 full size caprice / impala wagons with the 12" rotors. Use only the spindle, use the 1LE rotors and a caliper from a 78-81 camaro, and your choice of global west arms, Freeyellow or Hotchkiss arms. Those aren't the only players...just a few.

upper arms

If I don't want the expense of the tubular A-arms, which stock upper arm works, tha one from the Caprice? A guy can get the A-arms and the spindles from a salvage yard, and buy the rest at a chain store, one piece at a time. I'm working with small money here.

Here ya go:

Spindles and calipers are from 78-90 12" rotor (not 11") full size Caprice, Caddy, Delta 88, and Pontiac. Typically wagon or HD towing package.

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

Brake flex hoses, #BH36848

Brake caliper hose bolts, #483-205

Brake pads, # D52

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. My preference is the Global West conversion arms for 12" brakes, but Hotchkiss makes them, too.

thanks

:D Thanks, guys. Maybe tubular arms could come later. I have the parts from a '83 Z28 rear disc set up. I'm trying to use all factory parts.

Only the tubular uppers will work properly. The geometry isn't right with B-body uppers. The shim stack you would need would be taller than the A-arm mount studs.

That and the distance between the cross shaft bolts are 7.25" for a B-body vs. G-body's 6.5" distance-too much fabbing-not worth it. Buy good aftermarket uppers. -Jabin

Good point. I missed that one.

ouch

:( Well, there goes that. At this point, I can't justify that expense. As I stated in the original question, it seems someone did this years ago with stock parts. Since Car Craft, PHR, and other magazines were hot for these cars way back, I can't recall who did it, and the facts have grown vague. Thanks for the help.

I have a pair of assembled B-body spindle/1LE Rotor/Caliper/Carbon Metallic Pads/Dustshields, in good condition I'll sell for $300 plus shipping. They have a long service life left in them. Then all you need is the aftermarket upper A-arms (which I sometimes see on E-Bay) and a set of braided brake lines. They are off my 81 Bu from before I upgraded to Global West spindles/13" Wilwood brakes. The 1LE rotors are 5 on 4 3/4" stud spacing.

They weigh like 53lbs. per side, box for shipping.

PM if interested. I could post or send pix.

Yeah, shipped those suckers are heavy! I just sent a freshly built and powdercoated 1LE conversion kit to a customer in the Netherlands and it was pricey! I sent it USPS so it still saved him considerable money over FedEx or UPS. Rotors went in each box with dust shields, calipers in another, spindles in yet another box and then all mounting hardware, pads, braided hoses and bearings/seals in another. -Jabin

Warren/Tommy, Will the the 92 Camaro calipers and rotors work with this combo. Or YOU must use 1981 Camaro. Tommy what part numbers are your rotors/calipers from?

You must use 1LE rotors if you want to retain the bolt pattern. 92 Camaro calipers won't fit because they use a smaller brake pad-D154 vs. D52. You can use 70-81 Camaro calipers (1/16" wider than the Caprice w/12" brakes)for the job, too. I opted to retain the 5 on 5 bolt pattern so I used regular Caprice calipers. I think the part numbers Warren used is for A-1 Cardone reman. stuff. The OEM calipers for the 1LE swap are PBR dual piston aluminum and can be adapted fairly easy to our G-bodies but the brackets for the spindle are dis-continued now. You can buy the complete loaded kit through Autozone (P4747 I think) but what good is it without the right brackets? -Jabin

Dunno just how long Robert Adams has been doing his G-parts business, but he's a frequent player on Ray Buck's Elky reflector. He's a good guy and very knowledgeable. I haven't bought much from him but what I have, arrived soon enough with no problems. He's up-front and will tell you exactly what his stock and shipping times are.

Has anybody experienced,after the conversion, at top end when the car is slowing down it starts to sway and waunder ? I also installed the Trick Springs.
