in my 92 pickup- the brake light will come on shortly after passing about 35mph- Is there anyway to diagnose whats tripping this?

Not sure. My 93 flickers because there isn't enough tension on the e-brake cable. One is busted & I haven't felt like replacing it. Try pulling up on the pedal w/your foot to see if that stops it. /forums/images/graemlins/confused.gif /forums/images/graemlins/dunno.gif

body lift did mine in it stays on all the time but its adjusted correctly
Could be an ABS problem. The lights also come on when low on fluid but that usually just stays on, not coming on after 35mph... I would have the codes read and it's most likely an ABS problem. But check your fluid level to be safe.

could be, I know the ABS isnt functioning correctly. Heck, it isnt functioning at all. Could it be because the P.O put two different sized tires front and rear?

ABS only detects if the wheel has locked up or if it is spinning, I don't think that different size tires would matter. Is your 92 4 wheel ABS or just rear wheel ABS? If it's just rear wheel then it wouldn't know anything at all about the front tire size.

If it has 4 wheel ABS, the different size tires between front and rear will throw a fault code at higher speeds. The smaller tires will be spinning at more RPM's then the larger ones and the ABS module will pick up on this and set a code.
