change 98 jimmy brake booster Yahoo Video Search Results
I don't if that differs between manufacturers? I looked at rockauto.com for your brake booster, cardone part for your vehicle lists 97--2005 for your vehicle, brake booster.
If all the hook-ups are the same as the one your looking at, I don't know why it wouldn't work?
You know how it is, I see nothing from here.
I found it on rockauto for the 98 it was $114. But I found one for a 97 that was only $65. Saving money is a big deal with Christmas coming and all. Thank you! I found the information I needed from everyone! :)
Glad you got it going your way. I understand about the financial issues, I'm the same way.

Check the hardware for the drum emergency brake inside the the rear disc brakes, these pads are for your emergency brake, there should be an adjustment bolt that just sits between the two pads. Also, check the cables running to this set of pads to make sure they were connected properly. After you have checked the drum emergency brake, follow the cables in the undercarriage and look for the point at which they combine to another single cable, this is the point where the actual cable pressure adjustment is located.

SOURCE: Brake pedal still goes to floor 2000 GMC Jimmy
It's very possible to be the master cylinder, the o-rings on the piston could be worn, letting the fluid seep back through instead of getting full pressure through the lines. Could also be the brake booster.
Try changing the master cylinder first, which is cheaper and easier, and see if there is a difference, you'll need to bleed the brakes again.
To check the booster,
With the engine off, pump the brakes until the pedal is hard, then hold pressure on the brake pedal and listen for air escaping, or the pedal goes slowly to the floor, Do that after the master cylinder has been changed, at least that will be eliminated.
Testimonial: "Hadn't thought about the O-rings on the rod thanks for the idea. Great Idea Thanks!"

Do you by any chance hear a hissing noise from under the dash? If so, yes, you have a bad booster. For it to do what you're saying, it would almost have to have a vacuum leak. However, if there is a problem with something in the ABS system, you should have an ABS warning light on. Also, ABS can make the pedal fade, but I've never heard of it making the pedal hard. Your diagnosis of a brake booster does sound likely, but I'll admit I can't be sure -- this is an odd one.
Testimonial: "thanks, heard a hissing that i thought was coming from under the truck -- have to check tomorrow - actually my father's truck. have to get back there"
