Brake Grinding Noise Problems of Toyota Highlander

2007 hybrid abs brake actuator problem. The primer motor continues to run to prime the pump even when car if off. The humming noise changes when you press on the brakes to load knocking groaning noises. No dash warning signs. I bought this car used and it has always made the humming noise since I bought it. I thought this was normal for a hybrid. Sometimes brake pedal would push easily to floor, but then get tighter. I would hear the knocking grinding noise. No warning lights, had brakes checked and they are good. Thought maybe air in line. This noise and loose pedal started about 1 year ago. 6/2024 it did not happen all the time. I also have a company car, so I do not drive the Toyota Highlander that often. Now I cannot drive it at all. For fear that the brakes would go out. I started looking further online on information regarding this. It seems Toyota and Lexus RX 300 hybrids (same part model number) 44510-48060 are all doing this. I looked up recall's and nothing for abs hybrid problems. Just last week all warning lights came on in my car brake vsc. Reading all the problems with this abs actuator pump, this should be recalled. 6/2025 per online, it is a known problem with Toyota in the hybrid models. All of these units will need to be replaced, only a matter of time. Usually Toyota's run up to and overr 300k miles. I planned on keeping mine around. But it is a 2007 with 189k miles on it. I am not sure I want to invest $2000. 00 on just a part for a car this old! junk yards sell used ones for $800+. Same model number and only in time that will fail. Apparently Toyota has issued a new model number 44510-48061. There is also another new model 44050-48191. The replacement part (no labor) varies in price 44510-48060 new $1200. 00, 44510-48061 $1350. 00, 44050-48191 $2000. 00.

Brakes made metal/metal grinding noise. Found rear brake rotors badly corroded. Approx. 30% of both rotors functional. Seventy percent caked with thick rust. Driver's side rear caliper slider pin stuck. Front brakes did most of work, therefore pads are prematurely worn. In decades of driving, I've never had brake work before 80,000 miles. Car is used almost daily and always garaged. Rotor castings are defective and should have been recalled. Brakes have been inspected by Toyota dealer every 6 months. No problems were reported, but corrosion is severe, thick with flaking. I have dealer service records and photos to support my safety concerns. Toyota recalled 130,000 vehicles in china because of a defect in the rear wheel disk brakes which could possibly rust. Perhaps some of these rotors found their way on to our Highlander. My family and I have been driving an accident waiting to happen. Thankfully, no emergency stops have been required. How many other Highlanders have corroded, unsafe, brake rotors?.
