I posted a thread last week decribing a brake job that I did on my '93 2WD Explorer.
To recap, I
- Changed out rotors with Bendix rotors
- Changed out pads with Bendix pads.
- Changed out bearings with Timken bearings.
- Used Schaeffer 221-2 grease
- Tightened to 25 ft-lbs while spinning rotor.
- Backed off nut 1/2 turn.
- Retorqued to about 150-200 in-lbs.
After completing work, I had a roaring noise. I posted here and after rereading the Hyanes manual, I discovered that I had overtightened my bearings. However, I had I had only driven about 125 miles on them.
So, last Friday pulled all apart and redid everything. All bearings and races looked good. No heat marks or scoring. So, I repacked bearings again and this time torqued to about 20 in-lbs. Rotor free wheeled for about a turn after letting go.
Calipers went on and off easily. Greased the caliper pin slot with the wheel bearing grease.
Still hearing the roar and this morning after 20 mile trip to work, the front end smelled funny and when I bent down to smell closer, I felt the mags where very warm!
The brakes are stopping great!!!
Am I just going through the break-in of the pads and rotor or did I miss something?
The only thing I am wondering about was with my pads came a couple of anti-squeal shims and I did not put them on, but I am not getting any squeal.
One interesting note is that at the higher torque value, I did not have any wheel shake at 65 mph. However, I do now at the proper torque value.
What does everybody torque the wheel bearings to?
