Product questions
Which side of the vehicle does ACDelco 18FR1978 fit?
18FR1978 is listed as a front right, passenger-side disc brake caliper. Confirm the vehicle and existing brake configuration before ordering; it is not a left-side caliper.
Does 18FR1978 include brake pads and a mounting bracket?
The part-specific specifications list no brake pads and no mounting bracket. Caliper slides and mounting hardware are listed as included; confirm the supplied contents when requesting a quote.
Will 18FR1978 fit a 1972 Pontiac Ventura?
A catalog lists this caliper for a 1972 Ventura with the 4.1L inline-six, front right, with a metal piston and casting number 633. Verify the VIN or vehicle serial number, brake setup and casting before ordering; the model and year alone are not enough.
