Rear Disk Brake Conversion, Trying to Install, Major Problems, Help! Options

[coustoe]

K, spent all yesterday trying to install my rear disk brakes on my st.

Having problems:

1.emergency brakes will not work unless i pull additional wiring up through the e brake handle and use vise grips to keep the line in place, there seems to be tons of slack, and yes I've used the parking brake adjuster inside the parking brake shoe.

2. Caliper brake line from the junkyard has rubber hose cut off and thus no terminating screw or nut connection to connect to st brake lines, Question: can you by the GT caliper line and mate it to st brake line system?. Also I was thinking of using a hose connector to mate the caliper cut rubber line to the st brake system. Though I do not know if the simple brass connector will handle the force running through the lines without breaking.

For the e-brake situation... I can't say. i'd have to see it to figure things out... but for the most part... it should work if the rear-end is coming from a 5th or 6th gen. Minor adjusting is normal.

As for the brake lines... Go back to the junkyard and find some un-cut lines. There are two connection points, one on the body, and the other in the middle on the strut. You cannot use the metal part of the ST brake line, but the rubber parts should work (from the connector bolted on the strut). The calipers need more fluid flow and the small line doesn't fit, nor will it flow enough fluid. All you need to do is take another trip to the junkyard, and get some lines that can screw into the calipers, and then to the middle connector. They should be pretty cheap and most Toyota lines are very similar.

cool, I'll have to ride around with front brakes only for a while until i get the line in, Minor adjustments as in adjusting the screw right?

Well this is what is happening, got the adjustement screw and the ebrake handle at its tightest and the ebrake shoe doesnt move, if we pull the line tighter and clamp it with a pair of vise grips we see the ebrake shoe move and the wheels lock. so to make the ebrake work half decently we would have to soldering a new nut onto the line to make it tighter and pick the slack in the ebrake line.
