ok so i started out to replace my mc, turns out through it all i had to not only replace the mc, but the booster, front pads and rotors. and a brake line, now that its all togather the shop that my friend works at called me and told me that there is more problems
1. when hitting the brake pedal it goes 3\4 of the way down and then the brakes start to work, but if yu push it down any more then that the rear end locks up and kicks out.
2. the idle is fucked cuz it idles right below 1000 rpms then it will slowly drop to almost stalling and some times stalling.

i really dont know what the **** is wrong with it, and neither does the shop, does any one have any clue as to what should be checked, im have had to close my bank accounts inroder to fix this car and have run completely out of money, if i cannot not figure this out i am going to have to sell the car for enough to pay it off, wich leaves me really fucked. so any advise or info on things to check would be great.. btw its a 91 da ls .. thanks

 

1.did u bleed ur brakes?
2.check ur plugs/dizzy and all ur connections and grounds.

 

it wasnt doing this before i started all the work. i can deal with the idle problem its mainly the brakes locking up. my firend said that when he pushes the brakes it messes with the idle, so im thinking autozone sold me a shot booster, . but i will tell him to do that.
yes the brakes were bleed, is there anything else you have to do when disconnectiong a brake line from the pro valve

 

definetly bleed the brakes again, still air in the lines
as for the idle, i'd check all the vaccum lines into and around the booster, sounds like a vaccum leak

 

the first time i did all the work in my drive way and the gasket that goes between the booster and mc had fallen out and i didnt know it, so that and the brake needing to be replaced is why i had ti towed to a damn shop. the hose that comes off of the booster and runs to manny is good and so is that check valve my friend said he sprayed crab cleaner all over the place and couldnt find the leak. i really really love this car, and dont want to sell it but if i cant fix this problem then i cant work with out my car and would have to end up selling it to go buy a damn bicycle.. i know you have to adjust the booster pushrod mc clearance and tht should take care of the pedal having to travel 3\4 of the ways to floor and it might even fix the brakes locking up. but i dunno about the idle. any one ever ran into this problem?

 

whoa whoa whoa. There is a procedure for installing/calibrating a brake booster!

What shop are you taking to to? NEVER take it to there again. Any real master tech will be able to troubleshoot it.

 

its not the shop me and my brother in law snapped one of the 2 bolts that are used to mount the mc to the booster so me and him replaced that till almost 4am , the shop its at was told to replace a brake line and bleed my brakes then when they did it had the problems stated above...what is the proceedure, i know you have to adjust the pushrod to mc. but is there anything else, my haynes never said anything else about replacing the booster other then the adjustment of the pushrod.. my friend did all the work at the shop but when he got it all back togather and test drove it his boss said to stop messing with it and let there ace master tech take a look at it tomorrow, i am also supposed to go in tomorrow and check out the idle cuz it was idling alittle funny before i started all this work so i need to see if its the same idle. other then that its brake problem im think a brand new mc from acura should solve the problem along with all the adjustments that need to be done. so what is the proceedure for the calibrating of the booster and does any one know the specs of the pushrod to mc ?
