Front brake disk scraping on caliper during right turns

PostPost by: billmoore42 » Tue Aug 06, 2024 2:54 pm

Thanks everyone, I just rebuilt the calipers with new pistons and seals right after this happened, and the pistons move very freely in the calipers, and retract a bit after the brakes are pressed, so I don't think that is the issue.

Thanks for pointing out the odd alignment of the disk in the groove of the caliper. After trying tonight to tighten the hub a bit, I will then turn to looking at things like the caliper mounting bracket.

My thought on machining the inside of the caliper is it is a lot easier to get a new one if I mess it up, compared to something like the caliper bracket which is pretty hard to source.

Be carefull the Brake Caliper id a service part don't machine that. The Bracket is a fixed part. Either something has not been assembled correct or bent.
If you machine the Caliper it will make it a special and will be a pain in the Butt for someone else in the future

Problem resolved! I tightened the castle nut on the offending front hub by one notch, and the scraping of the brake disk on left turns has vanished. The hub still spins freely after a hot run, so I know I did not overtighten the bearings.

Thanks to Alan and everyone who advised me to avoid machining parts!
