yes i bench bled the master and the whole brake system, the first master i bought from o rielly's did that i returned it and got one from autozone and it doesnt leak. yeah after i replaced the master and bled the brakes the pedal got nice like how it was supposed to be i turned the car on and it depressed slightly like its supposed to do except the pedal slways stays down now. i rev the engine and you can see the pedal move up and get all its vaccum but still making the hissing noise and acting really weird. is there anything special i have to do to replace the booster?Originally Posted By: stevns71monteanyone?You need to determine whether it's VAC or HYD problem.. in the vacuum assist or the master cyl releasing its pressure. I'm assuming you bench bled the master cylinder & bled the brake system? Sometimes leaks in the master cylinder can allow brake fluid to be siphoned into the booster and play havoc on the diaphragm.. at times enough to be sucked into the intake manifold, signs of wetness on the inside of the hose are good tattle-tell signs of a leaking master. Also wetness under the master where it bolts to the booster, I've seen it drip (brake fld) into the inside of the car, right in the area of the brake pedal.. onto the rug.
To check the vacuum booster, pump the brake pedal with the engine off until you've bled off all the vacuum from the unit. Then hold the pedal down and start the engine. You should feel the pedal depress slightly as engine vacuum enters the booster and pulls on the diaphragm. No change? Then check the vacuum hose connection and engine vacuum. If okay, the problem is in the booster and the booster needs to be replaced.

anyone?

replaced master no luck. replaced check valve nothing all thats left is the booster itself, replacing that this weekend hopefully

i started the car and kinda layed down and put my head close to the brake pedal. it was really loud there. when i push on the brakes it stops, and it seems like when i push on the brake when its just idling the pedal stays down and my brake lights are constantly on. i checked the brake fluid level and its full.

how would i check or where is said diaphragm?

yes its coming from the assembly, and my brake pedal is really soft
-
ill start it and see but from inside is sounds like its coming from inside the dash

my brakes are acting up, i hear a hissing sound like a vaccum hose is disconnected but i checked all of them and they are good. but the pedal is weird i barely tap on it and my brakes lock up but it only does it on the first few minutes of driving after about five minutes of driving he pedal is fine until a red light then it hisses again and gets soft? i triple checked all the vaccum hoses that go into the brake booster what else should i check?

i do the exact same thing! everytime my guage has never read full even when i know it is full it takes about forty a week in gas :[
Gm gauges always seem to fluxuate from a 1/4 to 3/4
My truck reads full for about 4 days after a fill up,then drops real quick after that.
Are you sure your tank was full? Not just reading full,sometimes my Monte will take on plenty more gas after it first shuts the nozzle off, but most of the time,when it shuts it off, It pukes about 50cents on the ground
