The shoe spring is an important element of the drum-type brake system. After braking the car, such a spring returns the pads to the caliper, to its original state, which ensures the continuation of the unhindered movement of the vehicle.

The principle of brake shoe spring usage

Over time, any spring loses its elasticity. The tension is loosened, and the car's pads return to their original position incompletely or unevenly. This leads to the following consequences:

1. premature wear of pads and drum;
2. resistance to vehicle movement.

A sure sign that the brake shoe spring has already exhausted its resource is the appearance of noise and vibration during and after braking. This vibration can manifest itself as a pounding sensation when braking at a speed of 60-80 km/h. In these circumstances, the SWAG brand Spring, brake shoe may be the cause of the problem and should be replaced immediately.

As practice shows, the return springs of the brake shoes are especially vulnerable, as they are subjected to increased stress. To prevent increased wear and accidents, these parts need regular diagnostics (as part of the brake system check as a whole).
