rear discs brakes

Postby ggreen » 02 Dec 2008 18:55

From the photo's I have seen of the rear disc brake conversions it appears that the hand brake cable support bracket on the rear caliper is mounted on the reverse face of the caliper and is secured by one fixing bolt as appose to two. Can anyone running this set up enlighten me ?

Thanks guys for the quick response.

This is my point - some conversions show the mgf caliper with the handbrake support at 90 degrees to the caliper as in Paul W photo. The one I am querying is Beans wherby the support is at 45 degress to the caliper. This is the one I like as the cables are up higher and out of harms way. Both are using Rover 800/mgf caliper but with different support brakes for the handbrake and different levers on the caliper. My question is are these bespoke brackets on Beans or are they modified MGF brackets and levers or are they off the rover 800? Any ideas ?

Michael (V8Wedgehead),

Any chance of a description of what was done and the sources of your conversion parts?

Thx.

x2 Looks easy enough. I have a spare axle lying around that I can practice on [:D]

Can't save them all but I am trying!!!

The caliper is a Ford Tarus SHO 1989ish. They cost about 125.00 USD for a pair with pads. You want these and not the typical tarus because the spring for the e-brake lever is small and will not hit the rear coil spring on the SHO. If it does you need to use an inline cable spring and not the coil type for the lever.

Above is the correct spring on the caliper and top picture is of the larger spring that will hit your rear coil spring for the suspension.
The hose runs about 30 to 40 USD and the rotor I think is a ford Tempo that I had to redrill the lug holes. The iteresting part is the same rotor can be used on the front with a wilwood caliper and an adapter bracket. Back to the rear, you need to remove all of the drum brake down to the back plate. Use a slide hammer attached to the axle and pull the rear axle. There two ways of doing the next step. You can have a space machined for the same thickness as the rear drum backing plate or mark up the backing plate and cut it down to a square as you can see below.

Put the new spacer in and then reinsert the axle and tighten down the four bolts and the caliper bracket. Slide/gently tap the rotor on it is a really tight fit but a good one!
ImageImage
Put one caliper on and hoses. I have not worked out the e-brake cable adaption and the brake tubing for the flex hose yet so that is unknown territory. Right now it is a work in progress. Here is the bummer; a 13 inch rim will fit but not a steel TR7 or a TR8 alloy.

13x8 superlite rim plenty of room.

Fantastic write up Michael!!

Exactly what I was looking for. I'll have rear disks by, ah, er, sometime in the future :)

Interesting, I looked at Beans pictures. He made a set of spacers from the rear brake drums, but I have no idea why. Anyone know what they were for?

Maybe to allow for the stock steel 13 inch rims? It's the only idea I can come up with.

Can't help you with their origin as I bought the set up from S&S years ago (calipers are from a Rover 800 though)
Can only show you a picture of the bracket ...

Thanks Bean, that's exactly what I wanted to have a look at to confirm what I thought.
