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. -------------------- "It's ok to be naked girl... I'm an artist!"

[right][snapback]234269[/snapback][/right] 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.

Did you try searching yet, I remember reading somewhere on here you have to either use the 5th gen e-brake cable, or the 6th gen ebrake cable from a gt, or shorten the existing cable.

well if the ebrake cable isn't working and you tightened down the screw all the way,. then you are going ot have to modify the ebrake cable. This means cutting it shorter. I had to do that. Its not that big a deal. you'll have to go to the hardware store to get a piece that clamps around the end of the wire so it will stay in place.
As for the brake lines, I had the same problem. I had to get custom ones made. They are stainless steel and work really well. Ask a local mech shop for a place that makes brake lines/ fits them. I had mine in lesss than an hour. I would not drive without your rear brakes |

It all worked out though, I got some help from a local 6gc.net member |

I was hoping the gt line would just screw into the st line, so i guess i would have to make a metal adapter that mates the st rubber line to the gt rubber line? gah! |

[right][snapback]234888[/snapback][/right] The stock GT line is only one piece that goes from the caliper to the connector on the body. There is no middle connector on the facotry GT rear. The caliper uses really big fittings compared to the typical drums anyway, so I can't imagine making the ST lines fit. Also, it wouldn't be hard to find some other brake lines to fit... -------------------- "It's ok to be naked girl... I'm an artist!"

yeah, the ST lines do not fit at all. You will have to go custom or from a junk yard. Buying from toyota ain't cheap either.

ahhh, looking at the tires again in the rear and they are f*cked, i think we didnt put the spindles on all the way because the tires are slanting to one side majorily in a bad way.
I talked to a brake place and they said you cant just use clamps because the lines will still bust open from the pressue. Got time, can't do anything this weekend because of the snow storm coming in and next week ill be out of town for work. lame..... |

talked to the performance parts guy again today, said he would just make stainless steel lines, which i guess are better then the rubber ones that come with the gt.

You also need the GT caliper mounting brackets, and bigger (than 14") wheels.
