1973-98 Chevy GMC C10 C15 C20 C30 Truck Brake Parts
C10 and C15 pickups share this collection with heavier C20, C25, C30, and C35 trucks, creating very different brake requirements within the same Chevy and GMC family. Compare disc brake components, power and hydraulic assist systems, rear conversions, master cylinders, proportioning controls, lines, and service parts for 1973-98 truck applications.
Matching Brake Components to C10, C20 and C30 Setups
A C10 and a C30 may come from the same Chevy/GMC truck generation, but the brake hardware can diverge quickly once hub size, lug pattern, and rear axle configuration come into play. This collection reflects that split rather than treating every 1973-98 truck as one brake platform.
C10 and C15 applications have the widest range of front-end choices, including standard, BlackOut, and Wilwood wheel-component packages that can work around stock or drop spindles. Heavier C20 and C30 trucks follow a different route where 8-lug hardware and larger-duty components become part of the equation.
The difference becomes even clearer at the rear. A 5-lug C10 disc conversion and an 8-lug C20 system are built around completely different axle and wheel arrangements, even when the trucks share similar body years.
Farther up the hydraulic system, those model divisions become less rigid. Power boosters, BlackOut and Wilwood packages, Hydropower systems, master cylinders, proportioning valves, hoses, and fittings can be matched to the brake configuration, giving the collection a clear split between truck-specific wheel hardware and broader hydraulic components.
FAQ
How do I choose brake parts for my 1973-98 Chevy or GMC truck?
Begin with the exact year and truck series, such as C10, C15, C20, C25, C30, or C35. Then identify the lug pattern, front brake setup, spindle configuration, rear axle, rear brakes, master cylinder, and type of brake assist. Do not assume a C10 component fits a C20 or C30 simply because the trucks fall within the same year range.
What front disc brake options are available for 1973-87 C10 and C15 trucks?
POL offers standard disc brake wheel component kits, Deluxe Wilwood wheel component kits, and a BlackOut 5-lug wheel component kit. A Wilwood-caliper front disc conversion is also available for stock or drop spindle configurations. The best choice depends on the spindles and other compatible components already installed on the truck.
Can I convert a 1973-87 C10 to rear disc brakes?
Yes. POL's rear brake collection includes a 1971-87 Chevy C10 5-lug rear disc conversion, which covers 1973-87 applications. A BlackOut version is also available. Confirm the rear axle specifications, 5-lug configuration, parking-brake requirements, and wheel clearance before choosing a kit.
Are rear disc brakes available for an 8-lug Chevy C20?
Yes. POL carries a dedicated 1963-87 Chevy C20 rear 8-lug disc brake conversion. This is separate from the C10 5-lug system, so identifying the truck series and rear axle configuration is important before ordering. An emergency-brake cable set for C10/C20 disc conversions is also available.
What power brake booster options are available for these trucks?
POL offers a standard 1973-87 Chevy/GMC truck power brake booster kit, a BlackOut C10 booster with POL or Wilwood master cylinder choices, a BlackOut 2.0 system with a Wilwood master cylinder, and a chrome Wilwood booster kit. Vacuum hoses, booster boots, and pushrods can also be purchased separately.
When should I consider Hydropower brake assist?
Hydropower is an alternative to a conventional vacuum-assisted booster. POL carries a 1973-87 Chevy/GMC truck Hydropower brake boost kit along with systems paired with POL or Wilwood master cylinders. Rubber and stainless hydraulic hose kits, return lines, and mounting components are also available for completing the system.
What should I check before ordering brake parts for a modified C10, C20, or C30?
Check what is physically installed on the truck rather than relying only on the VIN or original specifications. Confirm the front spindles and brakes, rear axle and lug pattern, wheels, master cylinder, proportioning system, power-assist type, brake lines, and parking-brake arrangement. This is especially important on older trucks that may have received axle, suspension, or brake changes during previous builds.
