Overall Assessment

The product is highly regarded for its practicality and quality, with many customers noting its easy installation process and compatibility with older model cars like 1946 Chevy Style Master and 1957 Chevy. It has a neat appearance that enhances the engine compartment, suggesting quality materials used in its design. The kit's feature that allows switching from drum brakes to disc in front is particularly appreciated. Customers would appreciate more comprehensive instructions, specifically regarding booster and master cylinder plunger adjustments. Despite this, the strong compatibility with classic cars and simple installation process make it a favored choice.

Make sure you adjust space between booster and master cylinder. No instructions, but mine came way out of adjustment.

With more instructions, I would give it 5 stars. Bolts on booster interfere with top bolts on firewall. Need to saw saw one set shorter to install. Need instructions on adjusting clearance between booster and master cylinder plunger. Need to show which direction to install MC plunger rod (indent on booster side)
