Brake Drum Wheel Cylinder problems of the 2010 Toyota Corolla

Brakes are very spungy and do not seem to ingage. Brakes will fill like they are starting to work and then release and you must push brakes down further before they will start braking. Very slow braking response time. Had the brakes bleed twice and did not fix the problem so the mechanic replaced the master brake cylinder and the car braking did not change at all. Makes me very nervous to drive the vehicle due to slow braking response.

Then, the vehicle stopped when the emergency brake was activated. After the vehicle stopped, a picture of a tire was displayed on the dashboard. The vehicle was driven to the dealer mechanic. The failure was not duplicated; however, the brake drums were cleaned and the mechanic installed a cylinder slide and rubber grease. The caliper was serviced. The rear brakes were cleaned and adjusted. The manufacturer was not notified of the issue. The approximate failure mileage was 105,824. Bd.

The contact owns a 2010 Toyota Corolla. While driving approximately 30 to 35 mph on normal road conditions the "brake" warning light indicator illuminated on the instrument panel. When pressure was applied to the brake pedal there was a slow response. The driver continued to drive with caution. The warning indicator remained illuminated until the engine was turned off. The following day the vehicle was towed to an authorized dealer for inspection. The technician stated that the failure was contributed to a leak located on the right cylinder. The vehicle was repaired under the service warranty. The contact had concerns of the safety risk. The failure and current mileages were 260.
