Replacing the brake master cylinder reservoir (Chevrolet Aveo T300)

As practice shows, in many cases, overhauling the cylinder in a garage does not lead to the desired result. In addition, the main brake cylinder directly affects traffic safety. Therefore, this subsection describes only the replacement of the reservoir and the main cylinder as a whole.

You will need: pliers, punch, hammer.

1. Disconnect the wire from the negative terminal of the battery.



2. Unscrew the cap of the master brake cylinder reservoir...



3. ...grasp the edge of the mesh filter with pliers...



4. ...remove it from the tank...





5. ...and pump out the brake fluid from the reservoir, for example, with a large medical syringe. Install the plug to prevent dirt from getting into the master cylinder reservoir.



6. Squeeze the clamps of the brake fluid level sensor wiring harness connector...



7. ...disconnect the sender block.



8. On a vehicle with a manual transmission, disconnect the hose from the reservoir to the clutch master cylinder.

USEFUL TIP: Immediately after disconnecting the hose from the reservoir, plug its opening without lowering the hose down. There will be some working fluid left in the hose, then after installing the reservoir and connecting the hose to it, there will be no need to bleed air from the clutch release hydraulic drive.

NOTE: On vehicles with automatic transmission, the nipple is plugged.

9. Knock out the pin securing the reservoir to the master brake cylinder...

NOTE: Shown with master cylinder removed for clarity.

10. ...remove the pin...



11. ...and remove the tank, extracting its pipes from the connecting bushings.





12. If during operation a leak of brake fluid was observed through the connecting bushings, remove the bushings from the holes in the cylinder body.

WARNING: Do not reuse coupling bushings, replace with new ones.

13. Before installing the reservoir, insert the connecting sleeves into the holes of the master brake cylinder. Then install the reservoir by inserting its pipes into the connecting sleeves with hand force until they stop, and secure with a pin.

HELPFUL TIP: To make it easier to install the connecting sleeves into the cylinder and the reservoir pipes into the sleeves, wet them with fresh brake fluid.

14. Fill with brake fluid and bleed air from the hydraulic drive (see "Bleeding the hydraulic brake system").
