So I know it’s been a little bit but I have a new theory.
I got the one caliper warrantied and a second new one put on. This one does not drag or hang up like the last new one did.
however this is what I have noticed, the drive front wheel still has more drag than the passenger side. I’m pretty positive it’s the brakes. Taking the temperature the driver front is always atleast 10-15 degrees hotter than the passenger side.
and when you brake you can feel the driver side brake harder. Which led me to some theories
1. The passenger side is sticking/hanging up too. It’s not as old as the driver side only about 2 years old. But possible
2. the pads are more grabby on the driver side (not sure it would be constant)
3. I wonder if my steering knuckle is bent? When I was in highschool I was your typical dumb highschool kid and turned out in front of someone and they hit me right square in the front driver tire. I used to have the list of parts they replaced but now I can’t find it. But I’m pretty sure control arms were in there but I’m pretty sure the steering knuckle was not. This would make sense why the first caliper didn’t fit right and was binding. And possibly why this was is still tighter than normal.
The whole truck has newer calipers (same age as the pads)
new hubs
cv axles
Brake hoses
1 new caliper
1 caliper that’s about 2 years old
new ball joints
New tie rods inner and outer
So I don’t think those have to do with it. After highschool I went to tech school for autobody. While there I was able to put the truck on the frame rack and straighten the frame back into spec. That was several years ago.
If I get the chance I want to pull both tires and see if I can measure a difference between the left and right knuckles
A bent knuckle can show up in the SAI, included angle and turn radius numbers on the alignment end of things. You stated the brake was hanging up but no mention of new pads or rotors? Cooked pads/rotor on one side? Glazed frictions can be grabby. Ideally both sides need to be done at the same time. Wheel bearing ok? Is the rotor wore out where it has a ridge?
Measuring for a bent knuckle can be difficult. If there is a large discrepancy ok, but you you're dealing with measurements where less than 1/8 inch can make a huge difference and hard to do without a mini tram gauge or electronic frame measuring equipment. Typically a knuckle will bend just below the upper ball joint or in the steering arm section and on 2wd the spindle can get bent in which case the caliper and pads might not sit perpendicular to the rotor. On 4wd the hub would bend and make for a wobble. It's not clear in this thread which you're dealing with.
