crappy brakes

[pixiesfan78]

ok ive lived with crappy brakes for to long. it has new calipers and pads rotors look descent. pedal pumps up real good with the car off.drums look good.it just seems like im getting no stopping power at the front end.where do i go from here?when im sitting at a light i have to hold quite a bit of pressure on the peddal or it will start rolling i want to be able to tap the brakes and stop i want good response.any help will be appriciated.

more spacifically what is it that makes the calipers clamp down hard? it just feels like there not clamping down hard enough.

your not leaking any brake fluid are you?

[pixiesfan78]

no sir in three years ive never seen the level drop its been bled a few times. what about the type of fluid our cars require like dot 2 or somthing right what if its dot 3 would that make them suck i dont know what type is in there but its just a thought i had.

[86LXItooFAST4me]

are you Auto tranny or manual?

[pixiesfan78]

auto i know but hey im lazy and im a smoker.

[86LXItooFAST4me]

lol, i smoke and drive a stick. it is a hassle though. what is your idle when you at a stop? like what rpm?

[Mike's89AccordLX]

Our cars use DOT 3 Brake Fluid.

Are you brakes blead properly? How long has it been since you have flushed your brake fluid?

[pixiesfan78]

idle is about 900 to 1000. brakes are bled never flushed the fluid how do i go about that?

It sounds to me like you may have a leak at the brake booster. If you have a manual and a vacuum pump you can check it out yourself; if not, you may want to take it to a mechanic.

[pixiesfan78]

there is a little dusty old looking fluid around the brake booster but i never see any moist fluid.lxi why did you ask about the tranny?

[86LXItooFAST4me]

i was thinking brake booster too but thats one thing i dont know shit about is the brake booster, i wasnt even sure we had one. guess we do, lol.

[pixiesfan78]

i just went and looked at the booster i dont see any moist fluid my friend was saying that if the master cylinder is leaking fluid back that could be a problem like the o rings are bad in the cylinder so its not creating enough pressure.he also said that the brake booster should not cause it to be spongy it may make the pedal hard to push but not spongy.

[pixiesfan78]

if ther was a leak at all i should be able to hold the pedal down with the car off and it would slowly drop down thats not the case it pumps up solid.

[86LXItooFAST4me]

i thought when the booster was bad that it WAS spongy?

man i forgot about that, i had the sam thing. i had to replace my calipers though so i had to remove them anyway.

[pixiesfan78]

when i replaced the entire calipers i was very carful to clean and buff the pins and lube the hell out of them so thats not likely but ill check it to be sure.keep em coming guys ive got to figure this shit out.

[86LXItooFAST4me]

what happens it your going about 30-45 mph and you have to stop dramatically. do they lock up, or does like one or two tires lock up? what all happens?

[pixiesfan78]

ive got one wheel off now can i start the car and have some body hit the brakes with the caliper off to check for free movement from the pins?

[pixiesfan78]

no they dont lock up it slows down way to slow ive driven other accords and its like if im doin 30 and brake hard it stops in like ten feet my car i get like twenty feet. it brakes evenly though it dosent pull to one side or anything.

[86LXItooFAST4me]

man, im stumped. id have to look at it. im passing the ball.

the only other thing i can think of is soft brake lines or the proportion vavle
