Re: 86 civic si brake conversion help needed

Well, it's all done. i did the swap the weekend before last. started at about noon on saturday and got done about 6:30 sunday. Everything went pretty smooth but i had to go back to the junk yard and pull 4 of the longer bolts from the teg. somehow i forgot to get them the first time. and you need these longer bolts for the back because the calipar mounting bracket is thicker than the what was used on the civic drum setup. the front was cake, had all the old stuff off( calipar, brake lines, rotor)and new stuff on in twenty minutes. I also got the MC from the teg and one from a 87 prelude. The prelude MC is the same as the teg 7/8 bore so either way you will have to grind down the flange to get it to fit in the civic booster. I didn't go the get the whole rear axle route. i just took off what i need from the teg. to do the back you should get a 9/16 deep socket because there were a couple of bolts that you'll end up having to tighten with a box end wrench if you don't have the deep socket. the rear drivers side was pretty easy. just take everything off the civic so that all is left is the spindle. switch out the 4 longer bolts from the teg and reassemble with the new teg parts. On the rear passenger side you will have to take out the control arm bolt on the bushing end so you can remove it enough to get to the bolts you need to replace with the longer teg bolts. once those are inplace its same as the other side. The emergency brake lines fit in the stock civic e-brake location. only one of the mounting points didn't line up so i just made new holes and used the brackets from the old e-brake lines to mount it up. the biggest pain in the ass was the proportioning valve. the lines just didn't want to come loose. i spayed them with PB blaster on saterday and let them soak untill sunday afternoon and i still ended up getting a small pair of vise grips and using tape to hold two small pieces of metal on the teeth so they didn't mess up the nuts. after i got that all replaced and bolted up i bled the system and then went over all the nuts and bolts to make sure they were tight and torqed down. and i still missed two. Took it out for a test drive and it was really soft and didn't stop that well. i also was hearing a clunking noise comeing from the front end. turned out that the clunking was coming from the calipers. the outside peice where the pad goes on was not bolted down tight enough because it had loosend up after a couple drives. Also, the pedal would have pressure at first but would then fade to the floor at stoplights and stuff. i couldn't find a leak at first but then noticed brake fluid on the inner front fenderwell that was leaking from a very small hole in the right front brake line that i had got from the junk yard. make sure you wash all the dirt and whatnot off of the brake lines and check them extremly well for holes. on monday afternoon i took it to my machanic and had him do a quick check of the hole thing, turns out that there are two washers per calipar that you need to use where the brake line mounts to the caliper. for some reason i dindn't notice this on the civic calipers and the one brand new caliper that i bought didn't come with them. I'm sure they would be included if you bought new brake lines though. Now, two weeks later things are great. the improvment is so good over the stock civic brakes. I have 205/45 17x7 nitto neo gens on and they are so grippy that i almost have to use both feet to get them to lock up....thing stops hella quick.if i could put bigger rotors on, it would stop insanly fast. I know its kinda over kill, but i used drilled and slotted rotors with EBC green pads up front and the stock rotors and pads in the back. I drive alot in seattle up and down the hills with a loaded car and with the stock civic brakes i was getting alot of fade at the bottom of some of the steeper hills. not so at all with the new setup. There has already been one time where if i would have had the stock brakes i most likely would have ended up in the back of someone. I was going to take pics of all this but ended up not doing it. I still have to replace the control arm bushings so when i do that i will take pics of all the new stuff.
