Bleeding brakes Toyota Camry

Rice. 6.15 . Fill with fresh brake fluid

Use only fresh DOT 3 or DOT 4 brake fluid.

Bleeding from the hydraulic drive of the working brake system is necessary to remove air, which significantly reduces the braking efficiency. Air can get into the hydraulic drive due to depressurization of the system during repairs, replacement of individual components or brake fluid. The presence of air in the drive is indicated by an increased stroke of the brake pedal and its “softness”. Before bleeding, check the tightness of all brake drive units and their connections.

In the process of pumping the brake system, the level of the brake fluid should not fall below the middle of the reservoir of the hydraulic drive of the service brake system.

Bleed the brakes in the following sequence:

1 – the back right working cylinder of a brake;

2 – the back left working cylinder of a brake;

3 - front right brake caliper;

4 - front left brake caliper.

Raise the vehicle.

Disconnect the brake pipes from the master brake cylinder.

Rice. 6.16 . Gently depress the brake pedal

Gently press the brake pedal and hold it ( Fig. 6.16 ).

Rice. 6.17 . Release the brake pedal

Plug the outlet holes of the brake cylinder with your fingers and release the brake pedal ( Fig. 6.17 ).

Repeat the operations three to four times.

Rice. 6.18 . Bleeding the brake system

Connect a vinyl tube to the union of prorolling of the wheel brake cylinder ( fig. 6.18 ).

Press the brake pedal several times, then, while holding the pedal down, loosen the bleeder screw.

When the brake fluid stops coming out, tighten the fitting, then release the brake pedal.

Tightening torque: 8.3 Nm.

Repeat bleeding operations until air bubbles no longer appear in the outgoing brake fluid.

Repeat the bleeding procedure for each wheel.

Check the brake fluid level in the reservoir and top up if necessary.
