Can sloppy cam-bushings affect foundation brake integrity and performance?

  • Are the cam-bushings loose inside the spiders?
  • Can you see or feel damage inside your spider’s cam-bushing channel?
  • Have you tried rebuilding the surface with welding processes without success?
  • Are the spiders welded to the axles?
  • Is brake stroke causing you compliance problems?
  • Are the brake shoes unevenly worn?

Axle replacement is NOT the only alternative.

How would you like to rebuild damaged spider bushing channels on the spot?
