vehicle is a 90 integra sedan GS (ABS but doesn't work).

the FR brake hose broke couple days ago so i replaced it. most of the fluid from the reservoir was gone but i filled it up. today, i bled the brakes. starting with the RR caliper, i couldn't open up the bleed screw so i moved on to the LR. that was fine, no air came out. went to the FR caliper, bled it until no air came out. bled the FL caliper after that.

the guy that was pumping the brakes for me said it was still going straight to the ground so i kept bleeding the front brakes. all of a sudden, the FL bleed screw wouldn't let anything out. no air and barely any fluid. so i told my friend to keep pumping the brakes. he pumped it 10 times then hold, then i unscrew the bleed screw and still nothing. we did this like 5 times and still nothing. the brake pedal goes to the floor with barely any effort. there's still resistance but not normal.

to bleed the brakes, you start from the farthest working your way closest to the MC, right? RR, RL, FR, FL (is that right?)

also, my friend could spin the FL hub while i'm pressing on the brakes but cannot for the FR side.

could my MC be done? booster? oh and the brake pedal doesn't get stiffer when you pump the brakes when the engine is off or on

someone help, i have no other way to get to work tomorrow so i'd like to fix this right away. i'm mechanically inclined and know my way around cars.

i find it really weird that the front driver side bleed screw would all of a sudden stop anything from coming out. is it possible that something may be blocking the hole before the bleed screw ?

 

keep bleeding it out, dirt is in the lines try to get the bleeder open on the right rear, and if you still cant get a good pedal try a new mc.

 

your problem seems that u have a shitload of air in the system. you can try bleeding it @ the master cyl. same procedure like doing the bleeder screw. i believe the bleeding sequence is RR, LF, LR, RF. yeah, i know it sounds weird but i had to bleed my 94 civ like that. first of all what kind of wrench are you using to crack the bleeder lines? you should use a brake bleeder wrench (if you're not using one already) 8mm and 10mm. the wrench heads are 6pt. and the head part is deeper so you have a better bite on the bleeder screw.

 

i got the RR bleed screw loose this morning and tons of bubbles came out when i gravity bled it. i couldn't finish the rest cuz i had to go to work but i will tonight. i hope its just that cuz i already spent money on a tie rod, LBJ, and a brake hose. i don't wanna spend anymore until next pay day.

i read my manual and it said to bleed RR, LF, LR, RF so i will do just that. thanks guys! i'll post once i'm done bleeding the system

BTW, is it normal to make a squishing sound when i step on the pedal ?

Yeh thats right.

You could also back-bleed the system, basically force the fluid the opposite way up the pipes. There are back-bleeding kits available or you could make one up with some class of pump that'll stand up to brake fluid. Integras can give problems with bleeding calipers, it's not unusual.

 

i bled the system and the RR and LF brakes have no pressure. when the brakes are pumped several times, then held down, once i release the bleeder screw nothing comes out ?? but the RF and LR have pressure

there's nothing blocking the bleeders cuz if the pedal is pressed and the bleeder is released at the same time, fluid squirts out. i also made sure the reservoir was full at all times

what could the problem be ?

 

same problem with mines, sound like you need a new master cyl.

 

i'm almost 100% sure that its the MC cuz my booster is good and the symptom of a bad secondary piston in the MC is like i described it - lack of pressure on the RR and LF brakes

only if i knew not to pump the pedal all the way to the floor my car would still be fine right now

 

problem solved. it was the MC.
