Removal Procedure

WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 2.2L (L61).
  2. Remove the master cylinder mounting nuts (10).
  3. Move the master cylinder and the proportioning valve assembly or the antilock brake modulator assembly forward just enough in order to clear the studs on the brake booster. This flexes the brake pipes slightly. Do not bend or distort the brake pipes.
