What owners say about the service brakes
Verbatim from NHTSA complaints, newest first
“The vacuum pump. This vehicle was inspected by Dunn Tire. Yes, the vehicle is available for inspection. The safety issue that occurs is the loss of power assist to your brake system, and if not repaired, can impact the camshaft or the oiling system. (Please see attachment).”
“The Break booster has failed or started since the break fluid is leaking inside the cab. And other trucks from the same year as my truck did have a recall for the break master cylinder failing. My breaks could potentially go out fully and I wont be able to stop. My problem has been confirmed by my independent service center. And also there's alot of other people having the same issue online. Since the floor mats show oil stains just like how I found out I was having a issue.It hasn't been confirmed by the manufacturer but I will be taking it soon to be inspection but since a recurring issue with multiple trucks online. I wanted to report it here so the recall could be extended to other trucks from same recall year. I noticed i was having a problem when I had to press down the breaks really hard to come to a stop. Then thats when I stopped and saw the oil on the floor mats. And my truck has really low mileage for the year and its safety concern to me and being that the replacement is really expensive just the part is around 1200.”
“The brake actuator assembly is leaking brake fluid and is dripping onto the brake lever and onto the floorboard. This concern has been inspected and confirmed by a local Toyota dealership. This problem is a known safety recall by Toyota (Safety Recall J06).”
“The master cylinder is leaking brake fluid into the cab and is dripping behind the brake pedal. There is brake fluid in the wiring harness that goes to the brake switch as well. This is a known fire hazard from other vehicle manufacturers.”
“I own a 2018 Toyota Tacoma TRD Off Road and am experiencing a minor brake fluid leak within the cab which is leaking brake fluid from above the brake pedal. An independent mechanic determined the issue is associated with the brake booster and brake master cylinder which is related the failure to NHTSA Campaign Number: 18V888000 (Service Brakes, Hydraulic); however, the VIN is not included in the recall. No warning lights are illuminated. The leak was noticed at approximately 87,500. Vehicle is available for inspection and not yet inspected by the manufacturer, etc. The leak is minor now but believe it will get worse.”
“I HAVE HAD BELOW ISSUE AT 57000 MILES ON MY TACOMA. I WAS TOLD BY THE DEALER THAT I AM NOT UNDER THE WARRANTY, AND COPORATE THAT THERE IS NO RECALL FOR MY TRUCK BY SEARCH VIN, BUT ITS CLEAR IM EXPERIENCING THE SAME ISSUES AS BELOW AND SEEING OTHER VIDEOS ON YOUTUBE EXPERIENCING THE SAME ISSUE, SO ITS CLEAR THIS TRUCK WAS BUILT WITH THE SAME DEFECTS. The Plano, Texas-based manufacturer sent a safety recall report to the National Highway Traffic Safety Administration (NHTSA) stating they will recall 6,046 2018 Toyota Camry, 2018 Toyota Highlander, 2017 Toyota Sienna, 2017 Toyota Tacoma, and 2017 Lexus RX350 vehicles built between Oct. 2 and Nov. 3, 2017. Toyota stated in the report the affected vehicles contain brake booster vacuum pump assemblies with improperly machined oil galleys. The vacuum pump is supplied oil from the engine to seal and lubricate the pump vane’s movement. The defect can cause oil to not properly circulate through the system, eventually breaking the pump vane and causing potentially dangerous braking assist loss.”
