<VV> Re: Brake Lining Thickness

[Frank DuVal]

Brake Linings and Disc Pads

3. Riveted linings or disc pads are worn to less than 2/32 of an inch 
over the rivet head(s).

4. Bonded or molded linings or disc pads are worn to less than 2/32 of 
an inch in thickness or are worn beyond manufacturer's specifications.

5. Wire in wire-backed lining is visible in friction surface.

6. Snap-on brake linings are loose.

7. Any lining is broken or cracked so that lining or parts of lining are 
not firmly attached to the shoe or has cracks on the friction surface 
extending to the open edge.

8. Grease or other contamination cannot be satisfactorily removed from 
the lining, drums, or rotors.

9. Rivets in riveted linings are loose or missing.

10. Any lining or pad is misaligned or does not make full contact with 
the drum or rotor.


I just checked the Virginia State Police  Saftey Inspection  web site  ( 
http://leg1.state.va.us/000/reg/TOC19030.HTM#C0070 )  and found the 
above information.  2/32 of an inch is  .0625":, or about twice what GM 
thought of as unuseable. Of course this means that a brake lining just 
bigger than  .0625" is  considered safe for another year's worth of driving.
