Brake shoe quality introduction

There is no systematic introduction to the quality of brake shoes in the industry for many years. Today, I will introduce the quality of brake shoes

1. A good brake shoe must have no rust and no pits on the surface of the material, so that the surface of the brake shoe produced by electrophoresis is smooth and smooth.

2. Good brake shoes must be R-angle boring, and the center line of the four R-angles must be guaranteed to be perpendicular to the panel, so that the brake can ensure that the contact surface between the brake pad and the hub is greater than 80%.

3, good brake shoe panel circular arc must be fitted with the brake pad arc. After the general brake shoes do a good job, welding will produce deformation, good brake shoes arc is plastic.

4, good brake shoes fine workmanship. Generally good quality brake shoes, electrophoresis is good, no burr corners without welding slag, rivet hole without welding slag.

5, R Angle center distance standard.
