Notes：
1. This kit will not work with the original ’55-’64 Chevy 4-wheel drum brake master cylinder. It does not have the capacity to supply the proper amount of pressure for front disc brakes. For best results, we recommend using master cylinder booster kit 910-31974 (disc/drum) or 910-35557 (disc/disc) with this front disc brake conversion.
2. Front drum-to-disc brake conversions also require a proportioning valve to be installed in the rear brake line circuit. The proportioning valve modulates pressure to the rear brakes which is necessary to prevent the rear brakes from locking up in an emergency stop situatiuon. Recommended master cylinder booster kits 910-31974 and 910-35557 incude an adjustable proportioning valve to allow for a proper installation of front disc brakes.
3. Some grinding to the steering arms may be required to achieve full turning radius.
4. If using the slide pins in the kit you must push the bushing/spacer out of the caliper ears to allow it to fit and some force will be required to get it past the rubber seal to allow the threads to engage into the bracket.
