Review on Cowlboy Replace Spring Tractors Trailers by Mark Harris

Executed 3 truck brake jobs this week. The handle fell off at the 1st brake shoe so I glued it. On the 3rd wheel, the bolts came loose and the shaft was bent by the weak metal. Does not work with Spicer nibs due to the small nib diameter. Worked well with Meritor/Rockwell Q and Eaton brakes but showed severe wear after a week due to poor quality material. I had to spend a few bucks more and get an OTC version. Maybe the material is better. This was written by a Certified Master Truck Technician with over 40 years of experience.
