In response to complaints about diminished braking performance, Toyota has launched two repair campaigns involving nearly 178,000 2007-2011 model-year Camry Hybrid sedans, according to Consumer Reports.

The first issue involves the potential for a brake fluid reservoir filter to get clogged, which can lead to the temporary loss of front brake assist. When this problem occurs, the driver may need to apply more pressure to the brake pedal to stop the car. To remedy the problem, Toyota dealers will install a redesigned brake fluid reservoir as part of a special service campaign. There will be no charge for this service.

The second issue, involving either a faulty ABS brake actuator or brake pedal stroke sensor, similarly may require the driver to apply more pressure to the brake pedal to stop the car. The ABS might malfunction as well. Toyota has issued a warranty extension — to 10 years or 150,000 miles, whichever comes first — so that any needed repairs of these parts will be covered free of charge.

Thus far, Toyota has decided against issuing formal safety recalls to address these brake issues — despite pressure from Consumer Reports to do so.
