SPECIAL FORMULA FOR EACH SHOE
Each car model needs the brake shoe with the appropriate specifications. Sigmauto is able to supply the shoe with the correct friction material for each vehicle model. Sigmauto produces and checks each shoe in order to obtain performance similar to the original ones by varying compounds and materials according to the needs.
RECTIFIED ON THE DIAMETER OF THE DRUM FOR A HIGH FRICTION COEFFICIENT
Contrary to brake pressure, the jaws work on the drum with a friction surface almost double compared to brake pads, this feature imposes a high mechanical strength to adhesive part with which the friction material is fixed, at the same time, the material itself must guarantee an optimal friction coefficient, trying to prevent blockages as much as possible. For this reason, our jaws have the rectified belts one by one to have the same diameter like the drum.
Brake shoes are equipped with an automatic log to provide a high strength register. The printed register corrects wear and avoids general braking problems.
