Installation Tips

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.
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.
Some grinding to the steering arms may be required to achieve full turning radius.

This fit great on my 55' 210, the cost is affordable, the instructions were easy to read and looks great in comparison to drum brakes. If I had to pick a con if there was one, it would be the part where you need to drill the spindle for the new cotter pin. Not hard but just really nerve racking.
