Just about every time I drive my truck over 10 miles on the highway the Rear Anti Lock light comes on. The tires are the same size all the way around. Its a very clean truck and seems very well taken care of so im not too sure what to think. I havent looked at it yet, its too cold outside haha. The rear is a little saggy so Im not sure if that would cause it? Has anyone had something like this happen?

 

I see three different trucks in your signature. Which one you asking about?

 

oops sorry. the 94. the others are sold.

 

Not to hijack this thread but I've got a rear anti lock question as well. My anti lock light works fine as it's not stuck on but every time I get on the brakes hard on a slick surface the rear wheels lock up and never release until I let off the brake pedal. I've looked online and seems the only thing I can find is regarding the anti lock light being stuck on. Where would a good place be to start trouble shooting why the anti lock isn't working? Thanks! I have a 95 4Runner V6

 

I have the same issue on my 93. I have flushed the brake system, and I'm talking over-flushed

 

Might want to pull the drum off and make sure they're not full of oil from a leaking rear axle seal. Oil in the brakes will make them grabby and prone to lock-up.

 

hmm ok ill check that out, thanks

 

These trucks don't have sensors at the wheels, the sensor is on the top of the differential. You can pull it out and have a look at it as it might have a bunch of metal slivers on it. That sensor is usually the problem.

I have found that the abs on these trucks is a joke. I usually end up disabling it and ripping the modulator out and put new lines in. Also it is not very smart. Right now I am not feeding the modulator with any hydraulic pressure and it thinks everything is fine.......

 

ok perfect, thank you! i wasnt sure if it was like 3rd gens where it has an abs ring on the axle with a sensor or what.
