Author Topic: Converting to rear disc brakes (Read 3268 times)

I'm planning on converting to rear disc brakes. I have all the bits and peices (I think) but I'm not sure where all the brackets for e-brake cables mount, or what position the e-brake activator arms bolt to the caliper piston. I could really use an expanded view diagram of the complete set-up but I don't have a TA shop manual.

Also, once installed, should I put an adjustable proportioning valve in front of the rear brakes? I currently have the factory valve used for front discs and rear drums.

Any help is appreciated. You can email direct to stanski@telusplanet.net

You should contact Maltese Falcon, who posts here -- he's done the entire swap and has it documented with pictures.

The master cylinder would be different as was already mentioned. Also, the power booster is different, a dual diaphram. And a disc/disc proportioning valve is needed to, although you could use the adjustable if you wanted to, but putting a factory type one on would be easier.
The 79, 80, or 81 supplemental service manuals should have the instruction on how to work on the rear discs, since 79 was the first year for them. I know the 80 does, since I have that one.
The owner of this website has the service manuals on CD for a reasonable price, so I suggest you get one of those supplements so you'll have the rear disc servicing information on hand.
