Question about 1989 Jeep Cherokee

1 Answer

Trying to STILL change out the master cylinder for my sons jeep. It is a 1989 Jeep Cherokee Laredo. The Master cylinders in the books at the shops show 2 ports on the right side but the one installed is 2 ports on the left side and one on the right. We have gone to 4 different shops and so far NOBODY can figure out which or why the master cylinder is different than the ones on the books. They continue to send us the wrong one. This Jeep does have ABS and is power brakes. So far we have not been able to get any help. He is doing this for a high school project and even the teacher can't help. They can't even find one that matches the one that is currently installed. Can any one help to let us know what is up with this and where to go or what to do.

I have manuals for 98% of the cars in the states from
1965-2010, and I checked your jeep plus 10yrs before
and after 1989. All I found was two line line systems.
I have seen these situations before, where the manufacture will use a different casting, so it can be
used in more applications.(with minor changes such
as plug a hole)Witch is what I suggest you do. Go to
a hardware store and get a pipe plug for the odd
hole. Just make sure the plunger rods are the same
length, and bench bleed the master cyl. including
the odd hole.(get all the air out)Install it, and bleed
the system. I hope I have been of some help.
Good luck.

if there are no leaks, and the brake fluid is full, then most likely the master cylinder is bad. were the brakes bled to try to solve this problem or did this problem happen after the brakes were bled. you really need to tell the complete history about the problem.

Jeep Cherokee 1989 brakes not working


abs module shouldn't keep the vehicle from stopping but the light will come on if there is a leak in the system you could simply disconnect the module to find out though I would check the master cylinder and calipers/wheel cylinders though look for leaks on the floor board (under the brake pedal) around the wheel make sure when you bleed the brakes you only add new brake fluid dot 3 or 4 any water or contamination can cause failure+abs light a bad booster/and/or/vacuum line will cause excessive pressure on the pedal but should still stop the vehicle. if the vehicle was ever wrecked there could be kinked lines but not likely

94 jeep grand cherokee laredo brake problem


Hi there!

Check for leaks at the slave cylinders and flexi hoses.

After several attempts of losing pressure - check the brake fluid level in the master.

If you arn't losing any fluid, You've got a damaged seal in the Master cylinder, or are drawing air in due to improper adjustment (excess travel) of slave cylinders.

Are you trying this with engine running? - How does this affect it (using servo assist)
