FAQ

Do you need a new master cylinder for a disc brake conversion?

• Yes, when performing a disc brake conversion such as the 1987 Monte Carlo SS rear disc brake conversion with Part Number 555-631474, it's recommended to upgrade to a master cylinder that is compatible with disc brakes. Disc brakes require higher fluid pressure than drum brakes, so a master cylinder designed for disc brakes will ensure proper braking performance and safety. JEGS offers master cylinders specifically designed for disc brake conversions to complement your upgrade.

Are disc brake conversion kits worth it?

• Yes, disc brake conversion kits offer significant benefits over drum brakes, including improved stopping power, better heat dissipation, and reduced brake fade. Whether it's upgrading from drum brakes to disc brakes on a GM A-Body or performing a 1978 Camaro rear disc brake conversion, such kits provide enhanced safety and performance. While there is an initial investment, the long-term benefits in terms of safety, reliability, and driving enjoyment make disc brake conversion kits well worth it for many enthusiasts.

What comes in a disc brake conversion kit?

• A disc brake conversion kit typically includes all the necessary components to upgrade from drum brakes to disc brakes on your vehicle. This may include brake calipers, rotors, brake pads, mounting brackets, hardware, and sometimes brake lines or hoses. Depending on the specific kit, additional items such as a new master cylinder or proportioning valve may be required or recommended for proper installation and performance. JEGS offers comprehensive disc brake conversion kits tailored to various applications, including GM A-Body disc brake conversion kits, available at JEGS.com.

How much does a disc brake conversion cost?

• The cost of a disc brake conversion can vary depending on factors such as the vehicle make and model, the quality of components included in the kit, and any additional parts or services required for installation. Generally, a basic disc brake conversion kit can range from a few hundred to several hundred dollars. More comprehensive kits with higher-quality components may cost more.
