Air filter replacement
The vacuum booster does not need to be removed to replace the air filter F.
Using a screwdriver or a metal hook, remove the dirty filter F, which is located under the pedal assembly.
Cut a new filter in area A and put it on the pusher, then press the filter into place. At the same time, check that the filter completely blocked the hole, thereby preventing the penetration of unfiltered air into the amplifier.
Check valve replacement
This operation can be performed on a vehicle.
Disconnect the vacuum hose from the vacuum booster.
Pull the check valve out by rotating it to remove it from the rubber sealing washer.
Check the condition of the rubber sealing washer and check valve.
Replace defective parts. Install the node in place.
