No, I'll investigate all that if everything else fails. Our weather has been crap so I haven't been out to try anything yet. It looks like today may be the day.

I'll update after line replacement and bleed. Should be here this week.

I would think it was the master cylinder but I've sat at a light for 5 minutes without having to pump the brakes at all, so I don't believe its seals are bad.



I've still yet to get out there and check for leaks and bleed them. Got busy and then yesterday was poring down buckets of rain, wouldn't be able to see leaks anyway. Today maybe.

rebelBullDawg325 mine are pretty soft, anyone who drives it tells me they are. never bothered me or given me any problems though

95YamJam I have all new brakes, calipers, pads, cylinders, shoes, lines and master cylinder.

They didn't really act right til i got a nerw master cylinder. I took it apart and the seals where gone in it just forcing the brake fluid back intot he cylinder when I would brake.

My brakes are as good as they have ever been but not the best i've ever had. The pedal is stiff once pushed down about an inch but it starts engaging right away. Mine does not pull at all. 40 mph hard stop with no hands on the wheel.

I usually use the trans to stop and slow more than anything. Even in an emergancy stop I have already downshifted and cluthed out.

The master cylinder is full. I've not had a chance to check for leaks yet. Today got busy.

Actually, mine doesn't pull at all.

Take it one step at a time since you just bought it. Check the master cylinder to make sure you have fluid, pull all the wheels and check that the pads and shoes are OK and the front pistons and rear wheel cylinders aren't leaking.

Two reasons, the key being they are 23 year old stock lines in a rot prone area. I had the lines in a '93 blow out on me during a test drive. Also, I'm going to be doing around 4 inches of lift so I bought lines of the appropriate length.

I'll research how to diagnose that and check it.



The rest of you make it sound like YJ brakes should be roughly like what I'm used to so these sound pretty well hosed. I'll be doing a full physical check on them today.

natax My brakes aren't stiff, but not soft. Though with 33s I don't expect to stop on a dime, though I can stop relatively quick, when needed. (Damn lights that change at the last second and make me slam on my brakes)
04-21-2012 08:47 AM
joedob My yj brakes are very responsive and barely need to touch the pedal. I agree that you need to check fluids and parts and bleed lines.

crosma Thanks, I have new brake lines coming as suggested by another person since they are stock lines in an 89' . I think I'll still bleed them tomorrow anyway.
04-21-2012 12:29 AM
Drix Sounds like you need to bleed the lines.

How should YJ brakes feel?

Bought my first jeep yesterday and the brakes are taking some getting used to. I'm used to brakes that firm up and then you just push harder for more braking force. My YJ brakes go smoothly to the floor with almost no resistance but at about half way down the brakes start to work, at an inch or so from the floor they are at full force and pretty much lock up.

Is this normal or should I be replacing something?
