Brake caliper bolt and thread size?

[A ron]

Is there a standard size for bolts that fasten the caliper to the spindle? Hoping I have the wrong bolts, but thinking the threads are stripped. What do you guys do in this situation? Tap and die new threads?Cut the bracket of the caliper and weld another one on? Buy new spindle or spindles?Leave it and keep running three wheel breaks?Owner was running the car without the caliper on the RF, said he kept it shut off all the time anyway. On a 98 GRT.

If the threads are stripped out of the spindle use a long bolt and put a nut on back side if the plate that's what I've always done.

Just off the top of my head I think they are a 7/16 fine thread bolt. Please correct me if I am wrong, I am old.

Some are 7/16 fine and some are 7/16" corse. Even if they threads are fine you should
Still have a nut on the back side as it makes a mess when caliper bolts fall out

7/16" fine with a lock washer AND add it to your weekly check list. Just get a wrench on them to make sure nothing is backing off...takes literally less than a minute to check them all so well worth the time.
If you strip one just put a nut on the back of it but be careful of potential clearance issues with your rotor.

You guys are great thanks. Yea that was my only concern with the nut is clearance with of my rotor.

some grt s have a dynalite caliper which has a 3/8-24 bolt the superlite style has a 7/16-20 so if you had dynalite and switching to superlite different bolts are required
