G-Body rear disc conversion

[Kinetic Dan]

Is there a cheaper method of converting to discs on the rear of my '79 Cutlass, other than the $800-$900 off the shelf kits that I have seen?

i have seen disc brake brackets that you weld to the axle housing.They use third gen camaro calipers and rotors.the problem lies with in mking a bracket to hold the axle in the housing,and not lose all the axle lube.These brackets are for 9" housings that have full floating ends on the axle tubes.I'm sure that they will work on regular 9'' housing ends,if you can stop the fliud from leaking.You will need some kind of proportioning valve to hold the rear pressure where it needs to be.Ive done this swap before on my trail jeeps.I'm working on doing the same swap on both my bu's(72/79).Ive got a few ways to adjust the rear basis on the brakes. hope this helps.

That price is not far off once you consider what mc, prop. valve and rear kit to go with. I have about that much in mine but that's the total cost-rear kit, calipers, pads, lines, master cylinder, booster and prop. valve and all the little misc. hardware. There are certainly more expensive kits out there but mine are mostly all GM parts and you can use the WS6 or Caddy type E-brakes but I elected to leave my e-brake off my personal car. Otherwise, there are pinion mounted E-brake kits for Danas or 9" Ford rears, too. -Jabin

I've seen cheaper kits, for around $300 but they have no rear e-brake capability, and over here in the UK, its a much for yearly inspection.

I've found this rear disc conversion that has e-brake for under $400, seems a good deal as gathering all of the parts from other cars would probabyl cost around the same?
