Abstract
A vehicular brake apparatus includes a disc brake mechanism that brakes rotation of a wheel by pressing a friction member against a brake disc. The vehicular brake apparatus has a wall thickness detector that detects a state of wall thickness of the brake disc, and a controller that controls a state of contact between the brake disc and the friction member. Based on the state of wall thickness of the brake disc detected by the wall thickness detector, the controller controls the state of contact between the brake disc and the friction member so that the friction member contacts a relatively great wall thickness portion of the brake disc more strongly than the friction member contacts a relatively small wall thickness portion of the brake disc. The brake apparatus is able to eliminate the wall thickness variation of the brake disc or suppress occurrence of a wall thickness variation.
