Removal and installation rear wheel brake cylinders (Opel Vectra A)

Removal

Unscrew and remove the brake fluid reservoir cap.

Fill the reservoir with fresh brake fluid to the top edge.

Screw the cap back on and seal the vent with adhesive tape. This is to prevent brake fluid from spilling during the work.

Remove the brake drum.

Remove the upper return spring.

Loosen the brake pads slightly.

Clean the brake hose connection point. Loosen the union nut of the hose without unscrewing it completely.



Loosen the brake cylinder mounting bolt.

Installation

Place a rag under the brake shield.

Loosen the brake hose mounting nut, disconnect it and immediately connect it to the new brake cylinder. This will cause some brake fluid to leak out.

Tighten the brake hose union nut to 16 Nm.

Install the brake pads opposite the brake cylinder pistons.

Install the brake drum.

Remove the adhesive tape from the brake fluid reservoir vent.
