BRAKE PEDAL EFFORT WHEN COLD

Model and Year:
1990-91 GEO STORM


Some 1990-91 GEO Storms built before the following listed breakpoints may receive comments of firmer brake pedal effort when cold. This typically is the first or second brake application after the vehicle has been setting overnight. In the case of the SOHC base Storm, replace the 8 inch brake booster with a 9 inch booster. (This is the same one used on the DOHC GSI). In the case of a GSI 4-speed automatic, a new transmission controller with revised shift points has been released. Breakpoints and part numbers are as follows:

Base SOHC: VIN M7540581

P/N 94480242 - 9 inch Brake Booster

GSI DOHC: VIN M7524190

Auto 4-Speed P/N 97038520 - Transmission Controller


Part Availability:

Parts are expected to be available on April 13, 1992. In case of limited inventory, parts will be placed on 400 control to waive VIP surcharges. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. However, the parts will be shipped premium transportation at dealer's expense and all other order types will be placed on backorder until the 400 control is removed.
