I have a friend with a problem...

[Uncle Gump]

Close, 84 had RABS, a 94 had ABS.

Ive owned a few 94's with RABS.

I was thinking 96 up for four wheel ABS

My 93 had ABS before it was gutted for racing. I worked at a dealer when ABS was introduced.

No offense meant, but my 94 has RABS.

This from TRS History of Ford Ranger

1995 Ford Ranger –
A standard driver’s-side airbag was introduced, as was a brake/shift interlock for the automatic transmission. A 4-wheel antilock brake system became standard on all 4×4 Rangers, and on all with the 4.0-liter V6, but remained optional for other 2-wheel drive Rangers

Have not had time to get some pictures of the rear drums. Did you guys see the video I posted?

 

[Uncle Gump]

So yeah... I looked at the pedal travel in you video. Sounds like the engine was running?

If so... I'd like to see what it looks like with the engine off and vacuum assist pumped out so it's just full manual brakes.

If the pedal is still low with manual operation... I would have to say you might have air still and or rear brakes need adjusted. Drum brake adjustment is CRUCIAL to height of the pedal.

Also... even though the pedal is low... does it stop and hold the vehicle?

My 94 Ranger has RABS, and my '94 Explorer has 4 wheel ABS. I've owned several other 94 Ranger and B series trucks and none of them had 4 wheel ABS either but that's just a small sampling.

How do I do the vacuum assist pumped out??

Pump the pedal until you use up the stored vacuum. Two pedal pumps... maybe three.

I bet you're right, I was probably mixing up Rangers and Explorers. If that's the only 30 year old info I've forgotten I'd be lucky.

Update…. Took it off the jacks and took it for a drive. They are still not 100% but better than when I had bought the truck. Still have about 3/4 free play in the peddle before it does anything. It noticed if I pump it up I get better pressure but goes away if I don’t push the break after a few seconds.

Also with the truck off and vacuum pumped out, pedal if really firm

Hey Sean...thanks for the update. It really helps others who may be experiencing similar problems and the guys here really like to hear if what they are suggesting is helping or not.

Pedal fade typically means a leak...

Get rolling in reverse and stab the brake pedal several times.

If the automatic adjusters are working properly... that will automatically adjust any slop in your adjustment and bring the pedal up.

Hey Tom,
This is to help adjust the rear drums only, correct?

That is correct sir...
