3rd gen brake problem.

my brake pedal hits the floor.I had this problem before and it was because of a busted brake cylinder in the rear left drum.I fixed that and Ive been fine until now.I dont see any fluid loose.My pedal hits the floor now and I dont know why?

master cylinder will make the pedal go to the floor.A bad brake booster makes the pedal hard to push.

How can I test a master cylinder to see if it is good or bad?

if the pedal goes to the floor its bad.if it leaks its bad.

if you bleed the brakes,you will know if its making good pressure or not.if you have sombody pump the brakes up,and hold them down,as you open a bleeder valve,if it doesnt spray out of the bleeder valve,you have a problem in the master cylinder.If you dont bench bleed master cylinders,they might never work right,because the angle they used on install will hold air in the system indefinatly.

Will worn pads and shoes cause the pedal to go to the floor?thanks again hot rod.

oh yeah,and my fluid is a tad bit below the capacity.Will that cause the pedal to go to the floor?

Not in any case ive seen .Usually if the pads get too worn down,it will cause a leak in the caliper of cylinder,but the master should still have a good feel,cosidering the fluid isnt low.

unless its been ran to the bottom of the reservoir,it shouldnt cause any brake pressure issues.not enough to make it go all the way to the wood.

R master cylinders and boosters connected to each other or are they located sepratly in the vehicle?

the back of the master cylinder bolts to the front of the booster.

Is it a good idea to replace them both at the same time or is it okay to just install a new master cylinder?

You dont have to change them as a set,but if you find the master cylinder has been leaking out of the back into the face of the booster,the booster will likely fail due to the brake fluid destroying the rubber seals on the booster.

I just went and checked the master cylinder and booster and dont see any fresh fluid at all.Does a master cylinder have to leak any fluid for it to be bad.My car has been sitting for a few hours now and I also checked the insides of all the tires and dont see any fresh fluid?

they can be bad and not leak,wich is usually the case.

What if when I bleed the system fluid does squirt out the bleeder valve?I guess that would mean the master cylinder is good?
What could the problem be then?

that doesnt mean its good.if your not losing fluid and the pedal goes to the floor,you have either a bleeding problem,or a bad master cylinder

So that means if I have a bleeding problem I should see fresh fluid leaking somewhere right now.
Im pretty confident I dont have a leak anywhere so I think it might be the master cylinder.What do you think?

How many miles can a master cylinder under normal driving conditions before they go bad?

if you have a leak you will see fluid on the ground or on parts .If you have a bleeding problem,that means that air in the brake system exists due to it not being evacuated properly.

mayhaps rebleed the system,and get better results.

I see,but the braking system has worked fine for 15000 miles since I last worked on them until now.Will air that was left in there then be a problem now or do you think my master cylinder simply went out?I checked the car again and dont see any leaking brake fluid any where.

yeah its probably wasted. if expence isnt a big deal go ahead and replace the booster too.

I know for a fact that the master cylinder is original,How many miles can a master cylinder take before it goes bad?

Also,i forgot to mention that when I drive I have to pump the brakes in order to stop.It stops if I push it down to the floor once but stops better when I pump it 2 or 3 times.What does that mean.

same thing

same thing,meaning a bad master cylinder?

yes sir

thanx,I gotta go,the LAKERS are going to kick the Suns arrsss! :chair:

Is it me or does Kobe Bryant always throw up a brick when the games on the line. :bricks1: NE wayz,I installed the new master cylinder today and now I dont have to let ricers pass me by.Thanks everybody,my brakes r all good in da hood now.

By the way,I got the master cylinder at kragen for 45 bucks with resovoir.Get in the zone wanted 95 with resovoir.

cool. now go scare some old ladys

I know an old lady at the liquer store with a killer 70 trans am and she said she likes to smoke ricers.

thats kind of funny.I saw a lady who looked to be about 80 yrs,driving a shining new red corvette,and listening to somthing pretty close to lorena mckennett

it was a rather unusual feeling knowing that an old lady could prolly spank me in a race.

back when i had my 79 monte,an old guy who could barely get his head over his steering wheel,whipped me in a northstar caddy.

Dont you love it when youre driving a beater everyone trys to get you at a red light no matter who or what there in.Butt when in the firebird no one steps up.

nobody wants to race me hardly cause they can hear my cam over their radio,and can feel my car make the earth trimble in fear of the great smogger that she be

LOL :rofl:

i drive the 97'Crown Vic more than i do anything i got.Its got a 4.6 v-8,with dual overhead cams,fords answer to the northstar.its fast too,it looks like a cop car.When im driving the crown vic,People dont go over 70 on the highway,cause they get reminded of cops.But when im driving down the highway in the T/A,everybody all the sudden wants to do 85-90.

Yeah ,I slow down for cops but then I realize their taxi's

its like seing my T/A makes them put the foot to the wood

I just laid the ye olde smacketh down upon a Civic on my way home from the movies, he was revving his lawnmower at me.... :loser:

are you testing out a new hate mail filter silver87?Ha

How dare that ricer step up.I hope he learned.

No sirree, not at all...just statin a fact :D

Can I really be held accountable if my rumblin-ass Flowmasters and air-suckin ram air kit does something to the part of the import owners brain that desires a beatdown to take place? I think not :devil:

Now, I'm sure if he had Nitrous or something, I might have gotten beat, but all he had was exhaust, so hopefully I have inspired him to better himself and his rice....er I mean car :)

Hes got a good point.

some little *domestically challenged* cars come off the line like they are going to be all buisness.even if they get a few feet on me,they are usually about to go into third as im coming out of first.ive never had one hang with me thru half of third gear.usually i can have them about rapped out in fifth and im on a sunday drive at like 4000-5000 rpm's.They more often than not find the nearest turn lane,after they hear the comp cam,400 SB heads,and dual cherry bombs.

Hey hotrod, r u going to tint ure windows because I think it will look cool on your whip

i have two layers of the darkest window tint.i will post a picture here in a second,in my gallery,but as for the back or front i will not because of the safety factor

whaddaya think?i bet they are not exactly legal but it sure keeps the inside nice and cool

Thats cool, Im going to get my gallary going as soon as my sis helps me so then you guys can know more about me and my whip.

what does whip mean?and am i going to feel stupid for asking¿

Well I listen to rap sometimes and I hear rappers calling there rides whips.You know something that whips you around,like youre T/A :rofl:

hey everybody,I opened A thread called PEOPLE WITH SHOPPING NEED INSURANCE.gO TO coffee break, strees release,Id like to here what you guys have to say in there.

I forgot to write carts after shopping.
