Helping a friend with his new chevy brake conversion.
Normal braking is great, but going faster or slamming on the brakes causes it to pull to the left.
Last winter it got new steering linkages, bushings, ball joints.
Everything is new on the brakes except the prop valve, the spindles and the flex line from the frame to axle.
Here’s what we’ve done so far with no success.
-tire pressure and tires size the same
-Bled about $40 in brake fluid thru the front right caliper alone
-Swapped pads R to L
-Swapped the new braided lines to the calipers R to L
-Swapped caliper mounting hardware R to L
-Plenty of caliper/knuckle clearance, calipers do not touch the knuckles even with no pads attached
-Swapped the calipers right to left and bled off the brackets with the bleeder screws up
-alignment done last month, toe correct, camber at .5 on both and castor at 1.9deg on both
When jumping on the front bumper, the steering wheel does not turn. But raising the frame with the wheels on the ground about 5or 6 inches and then dropping it does cause the steering wheel to turn to the left, but this seems out of normal driving compression.
As a last ditch, I took the calipers and brackets off my bronco and installed on his, still pulls to the left.
I had him drive towards me and slam on the brakes, I can see the front left caliper is clearly grabbing faster and harder than the right caliper.
Hoping I'm just missing something really simple here. I was thinking maybe the spindle is out of spec, but it behaves likes it's still a hydraulic issue
All thoughts and ideas welcome...
