Master cylinders and brake boosters play a critical role in the operation of your 1987 K35/K3500 braking system. The master cylinder converts pedal input into hydraulic pressure, while the brake booster amplifies that force to provide smoother, more responsive braking.
OPGI offers four Master Cylinders & Boosters designed for proper fit, performance, and durability. From master cylinders and power brake boosters to related components, you’ll find quality parts from trusted brands including CPP and Wilwood to help restore reliable braking function and pedal feel.
Every purchase is backed by our Price Match Guarantee. Plus, with OPGI’s 60-day return policy, you can shop confidently when selecting parts for your 1987 K35/K3500. Orders ship quickly, or you can visit our Southern California showroom to see select components in person.
