I have a 1991 S15 Jimmy 4x4 4.3L. Can anyone tell me the size of bolt for the caliper mount and also the bolt going from bracket to hub. Thanks.

 

The caliper is mounted to the spindle using a combination bolt/slide-pin. The bolt has 7/16-20 threads on it and I believe it is a 3/8" socket head bolt.

The bolts that bolt the wheel bearing/hub assembly to the steering knuckle (with the brake shield sandwiched between the two) should be M12x1.75 thread 50mm long and should have a 15mm hex head on them if I remember correctly.
