i have no brakes on my 89 xj, i dont feel anyxpressure when i start the truck, any tips, i looked for a vacuum line but saw nothing this 89 has like 10 lines going to it

when you push pedal it goes to floor ?

I have brakes but feel 0 assist when engine is on, have to slam on the brakes to slow down

so pedals hard a rock when pushed?

Pretty mucH

Bleed your breaks and try.new hardlines

The brake booster is vacuum actuated, so a leak could be the problem.
If you have a vacuum leak, your engine will be idling high even after it's warmed up (over 1500 rpm) so that should give you a clue.
If your brake's master cylinder is full, and you DO have brakes when you mash down on the pedal, (not pump) Best guess is the booster is gone.
It's only about $50 at the JY.

Carpe *******

Engine does idle high after warm which line is it? Not easy to spot like most cars , its an 89

pump brake pedal untill it get hard then start xj pedal should drop a little this will indicate brake booster is working properly .

this is the brake booster vacuum line ...

my xj is not like that

could my abs pump be bad?

you have abs thats completly different set up .

An 89 doesn't have ABS

Sounds like you have a vacuum leak.
If you can't spot it with a visual inspection, get a propane torch like you'd use for plumbing.
Turn it on without lighting it.
Use the torch to spray the propane gas on the vac. lines and fittings.
When you come to the leak, the engine idle will jump up because the engine is sucking propane.

Heres all info i ever found on it alot of people trash it and up grade to dual diaphragm booster ...http://www.aa1car.com/library/abs_bendix9.htm
