Repair of VAZ-2121
If necessary, the engine piston group can be dismantled on the vehicle without removing the engine
We carry out the work on an inspection pit or lift.
Usually we remove the master cylinder reservoir for cleaning or other work
You need to wash the reservoir with a soapy water solution, then dry it.
When the vacuum booster fails, the force on the brake pedal increases significantly, which negatively affects vehicle control.
If the force on the pedal during braking has noticeably increased, check the brake booster on a stationary vehicle
Disassembling the front brake mechanism
Hang up and remove the front wheel.
Removing the front brake hose
Hang up and remove the front wheel. Disconnect the hose from the brake cylinder block (see Disassembling the front brake mechanism).
We carry out the work with an assistant on an inspection pit or lift
If the handbrake cable is very stretched or jammed, it is better to replace the cable
If the parking brake system does not hold the car on a slope of up to 25% when the drive lever is moved by 4-5 teeth of the ratchet device, the parking brake must be adjusted.
