hey guys my 89 hatch is starting to have a pretty mushy pedal , the car still stops fine, But if you press the brake it goes down pretty far. . . If you pump them the pedal will get stiffer. any ideas?

 

check your pads and rotors, and if they dont look too wore out you should check your fluid levels and attempt to bleed your brakes. worst that it could be is master or slave brake cylinder

 

master cylinder is most likely the problem and if you change it yourself. Make sure to bench bleed master cylinder before installing it. My 1990 Honda CRX cost me around 75 bucks for master cylinder and fluid. Oh go new instead of a rebuilt bc saves you in the long run from brakes failing again

 

The car just passed state inspection the pads and rotors are fine, im thinking master cyl. . whats the diff. between the master cyl. and slave cyl?

 

im thinking master cyl. also , Thanks man

 

Welcome, Im a NATEF certified mechanic and im darn good with vehicles. Oh 93greyeg Pa is an awesome state

 

i have the same prob. but when i prees on it a few times consecutively then it jump idle for a sec or 2

 

ok.. want a cookie?

op: could be your master cylinder, but don't rule everything else out just yet. check all 4 corners and see if you have fluid leaking from anywhere. also, make sure the slides in the caliper are free and the pads are wearing evenly. how's the fluid level in the mc?

 

haha, No im not loosing any fluid at all, The master cyl. stays full.

 

My master cylinder was bad and it stayed full. I checked all four wheels for leaks and such. I had none. I just replaced wheel cylinders like two months before my master cylinder went out. I had my master cylinder go out drivin my crx around town. Not fun without brakes and then I figured it must be master cylinder bc no leaks in system.

 

yea im almost positive its the master cyl. I have no leaks anywhere and the master cyl. stays full.

 

well thats a good point I am positive its your master cylinder too Just hope you get it takin care of before you drive like i did with no brakes. It was just hope alone on usin ebrake for brakes LOL

 

you have some vaccum issue with your master cylnder

 

That's normal, All the cars I've seen do it

 

change it before summer comes. dangerous when your peddle sinks no brakes.

 

For sure the master. I can actually hear a vac leak in mine and the pedal is extremely mushy.I pluggd the vac hose from the intake to help high idle and basically breaking with no assistance its better then pedal on floor for now and its not too bad wit such a small car
