Title: 88 TC Brake Help!!!
Post by: Ether947 on October 09, 2005, 05:09:09 PM
I used the parking brake... which didn't work, and now my brakes are stiff and not very effective. I the ABS light and the parking brake lights are on as well. Can somebody please point me in the right direction???

sounds like the power unit has failed . maybe a relay or a fuse i would check them first.

Would anyone happen to have a layout of the fuse panel? Mine's missing. :(

Sooo what your saying is... I should get rid of ABS. :D I just drove it again and it is really bad. Like I really have no brakes. Just a wing and a prayer. Is yours like that?

mine is really hard and I only have front brakes.  I want to fix it right and have everything working as it should.  when I start getting my cash flowing again I'll see what I can do to figure out my problem.  the way that I handle my brakes is downshifting alot wih my foot on the brake.  give that a try.    I'll let you know what I find.

I would too... until I saw the price of everything. Converting to non-abs seems like a better option to me. I shall have to research it.

you can buy a good used abs unit for $50 or so but then you dont really know what your getting or how long it will last I think this is the route that I am going to take when I get down to doing the brakes.

try taking your wheels off and see if your e-brake are just stuck on i know when i was putting a new rear end in my car the new one had one side where the ebrake was just stuck and i had to break it loose.

Sounds like you have either faulty wiring or a dead pump. I ran into the same situation...ended up just converting to vacuum brakes. It's really not that hard, you just have to get a bunch of brake adapters which can be a PITA to find.

Well just ran some tests and the pump works but the relay doesn't so that's good news.

Post by: 88turbo on October 10, 2005, 06:14:36 PM
my pump will work if I ground the relay :dunno:
Title: 88 TC Brake Help!!!
Post by: Red_LX on October 10, 2005, 06:55:50 PM
Yeah, I could get the pump to come on if I jumpered the relay plug, but a new relay didn't do squat.

same here, what now?
Title: 88 TC Brake Help!!!
Post by: Ether947 on October 10, 2005, 08:29:21 PM
is this what you guys did?

Quote
Find the relay with the T/Y, GY, GY/R, GY/Y, PK/LB wires. Remove the relay from its socket, and jumper the T/Y and GY/R terminals together with a heavy gauge jumper wire. Turn the key to run. You should be able to hear the hyd. pump running in the ABS unit. If you hear it run, but don't let it run for more than 10 seconds or so. If you hear it run, turn the key off and put the relay back in its socket. Now, turn the key on, and depress the brake pedal several times and see if the pump runs.
If it doesn't run, probe the PK/LB wire (stick pin thru wire, etc), and, with key on, ground this wire. Pump should run. If it does, the relay is good, if it doesn't run, but ran when the T/Y and GY/R wires were jumpered, then the relay is bad.

i certainly hope i am not still screwed. >.<**

Yep, that's what I did.

Honestly, converting to vacuum brakes is not that hard...it's just tough to track down everything you need. Plus I seem to be having problems with brake fluid getting out from under the lid on my MC (I got one of the old-style mc's because I'm poor)

mine runs whenI ground the PK/LB wire after I replaced the relay so whats the deal?  I really hope I dont have to trace all of the wiring.  I havent tried jumping the other wires I'll try it when I get a chance

Mine doesn't run with the PK/LB grounded. So hopefully I lucked out. :)

88turbo: did you check the pressure switch?

Pull the connector off the pressure switch (5 pins). Put the relay back in its socket. Jumper pink/light blue wire to the gray wire in the connector with the key on. If the pump runs, the pressure switch is bad.

Here's a part number I found. E7SZ-2C244-A Anti-Lock Pressure Switch. $151.68 Looks like you have to buy it through Ford.

And you'd pretty much have to pull the MC to get at the pressure switch anyway...

I have everything from the pump to the master and other stuff that I took off my car a couple of months ago that I would sell for $70.  Worked then but I switched to manual brakes.

Ted, if neither of them want the stuff I'll take it. I'm planning on using the original ABS as long as I can(and I just installed my spare on the TC thundergrowl bought).

Just for the record, I replaced the relay with Part Sorenson MR14 and the brakes work now. :) Happy I is.
