While driving today ('95 Ranger, 130,000 miles, 2WD, rear ABS only), my ABS and parking brake dashboard lights came on at the same time.

Any thoughts on why both came on? I thought that it might be related to brake fluid levels, but those appear to be fine in the reservoir.

Is this something that I can possibly try to fix myself? I'm pretty good with my hands, but dont have a lot of automotive experience.

Thanks

 

it means that there is something wrong with your brakes, i was bored once and pumped the breaks at a really long light for entertainment and both came on but as soon as i got were i was going shut it off came back out and started it up no lights

 

Thanks for the reply. I have tried just shutting off the car and restarting, but it doesn't make a difference. I have also disconnected the battery cable, but it definitely returns again.

The parking brake light stays on as soon as I start the truck. The ABS light turns on when I start the truck, shuts off briefly, and then comes back on again after a few seconds.

Again, any more detailed suggestions out there? Thanks.

 

The parking Brake light is not just what it is. it is also a warning light for your master cylinder. check your fluid level. Hows you pedal feel? also the abs light is it on when you moving? check the Sensors at the front wheel and on the rear diff.

 

Check the fuse related to the abs, I pulled out a fuse months ago and both my p brake light came on along with the abs light. There are a couple related to the abs and one affects a few other devices then the others. I believe the one I pulled for the light show was a smaller 15-20 amp in the cab. The main abs fuse is in the engine bay. Could be simple as that

 

Thanks for the replies. I'll definitely try the easier ones first. Fluid levels are OK, so I'll check fuses next.

 

OK, its not the fuses in the cab. I'm trying to figure out which one is the right fuse in the box under the hood. My owner's manual seems to show a different configuration than what I'm actually seeing. My owner's manual says that there should be a separate set of relays near the left front wheel under the hood. But I'm not locating it.

I have been reading up on swapping out ABS sensors. I only have rear ABS, so I am thinking it's the block-shaped thing above the rear diff. Is that a difficult thing to replace?

Thanks for any other help.

 

The fuse box on my wheels is on the firewall above the master. And the abs sensor should be 1 bolt then hopefully the corrosion won't be a pain to pull it. Not a hard fix but defeniatly clean the area well and don't let junk fall into the housing. Pull it out as straight as possible. Grab one from the wreckers and give it a try. Can't hurt..

 

Both of my lights come because my brake proportioning valve is leaking- check for spots on your driveway. It drips out of the back of the valve and onto the frame then drips from the frame.

Anybody have any fixes for this valve? Ford wants too much for the part- $367.

 

^^^ Adjustable one from Summit Racing for like $70 or a used one

 

I'm having the same problem can't figure it out

 

I recently had the same issue. I changed the proportional valve and no more lights.

 

Where is it I looked for it I deff drove threw some water and next day done I swaped out the rear diff scencer did nuthing

 

Not sure about a 96, but on my 2000 it is in the engine compartment on the inside of drivers fender. Find the Master Cylinder (where you add brake fluid) and follow the brake line. It should go to the proportional valve.
