1990 Suburban brakes
My Suburban has recently started pulling to the left during braking, well the steering wheel turns , not so much the truck. So my first step was to change the calipers, and the problem is still there. The tires pressure is correct , theres plenty of fuild pumping through the brake lines and the master cylinder seems to be working correctly. Also i noticed it seems like brake dust collects faster than i remember. I dont know if they are related problems , but any suggestions would be helpful!Life's short... Drive hard!:sign0011:

Check the front brake lines to make sure they arent expanding under pressure, this happens a lot on lifted trucks.

Just get full steel braided brake lines, better in heavy braking and no expansion of the lines either, they are woth the extra $$. Also even an alignment/tire balance can cure brake pull99 K1500 Suburban LT "THE BEAST"

Turns out my left front rubber brake line was expanding, causing the RF brake to pull the truck to the right. What a PITA conencting the LF steel brake line to the proportioning valve,,, should have taken 15 minutes to replace the lines, took me 2 hours and alot of frustration. but the truck brakes straight now. So it's on to the next step WVO conversion.
