2005 Toyota Camry Binding Brakes
Grabbing brakes on 2005 Toyota Camry LE.
The car was brought in by customer with a complaint of grabbing breaks and noise from left front wheel while driving. On inspection of front disc brakes noticed that the left front caliper was hard to remove and the caliper piston was hard to push back. The ususaul thing we do is to first replace replace the brake hose the caliper and front brake pads. When we tried to remove the guide pins on the calipers to lubricate them,we noticed they were frozen after some effort we got the pins out and noticed they were rusted out.We ordered a new hardware kit cleaned the caliper bore installed the new pins after lubricating them with grease.
We then went for a test drive after driving for 7 miles we saw smoke coming out of the left front wheel. We then went to look for the bleeding sequence and bleeding procedure in Alldata and Mitchell both software said to use automatic bleeding procedure with a hand held tester. We did have the tool but the software was not updated.We tried to gravity bleed but nothing came out of the calipers even after an hour.
We then googled the problem for the vehicle and found a person had the same problem we were having and he had gone to the dealer and the dealer replaced the front caliper, brake hose, rotors and pads with the same problem Then the dealer recommended a ABS control module at a cost of $1300. The customer did not have the money and so he declined. The customer then thought that it could be a master cylinder problem and he replaced the master cylinder which solved his problem.The master cylinder has two chambers one for front brakes and the other for rear brakes.When the brakes are applied the fluid should flow into the caliper pushing the piston forward and the brake fluid should return to the master cylinder when the brake pedal is released.
We had to deliver the vehicle and we decided to do it the traditional way manual bleeding. One technician inside the vehicle push the pedal slowly and hold it down while the other technician had the rear right caliper bleeder screw open, when the brake pedal reached the floor the tech would close the beeder screw. The tech in the car would then pump the brake after the tech bleeding having tightened the caliper bleeding screw. We repeated the procedure for the other three wheels.
This technique worked for us as the system was never empty,we then test drove the vehicle for 30 miles and checked the brakes to be fine with no binding.
