Do You Have To Bleed Brakes After Changing Pads And Rotors
Camila Farah
In that case yes they would need to bleed the brakes.
Technically the only time you need to bleed the brakes is if something has been changed that s part of the hydraulic portion of the brake system. The only time you ll need to replace your brake pads and rotors is when the pads are worn and your rotors are warped though that doesn t happen often. So they open the bleeder valve on the brakes and then squeeze the caliper back in when they change the brake pads. Any brake job should include a brake bleed for safety s sake.
Rotors are engineered to last about. After installation of the pads and rotors pump the brake pedal until it returns to normal operating position and you ll be just fine. Pads shoes drums and rotors not necessary. As long as you did not open any of the bleeder valves which isn t necessary when doing rear pads and rotors then there should be no reason to bleed the brake system.
The front rotors have a minimum wear specification of 26 mm. Braking with worn pads requires more brake fluid which drains the reservoir and creates space for air. The key to servicing the brakes on the venza is to pay attention to the details like the lubricants and rotor dimensions. But on a lot of cars like toyotas and hondas you can just squeeze the caliper back in using a big wrench or clamps to squeeze them in.

If you find a leak. Leaks might not just let fluid out they could also let air in.
