How to Work on Brakes for 1978 Honda Twinstar 185
Are you a proud owner of a 1978 Honda Twinstar 185? This classic bike is a true gem, but as with any vintage motorcycle, it requires regular maintenance and occasional repairs. One crucial aspect of maintenance is working on the brakes. In this guide, we will walk you through the process of working on the brakes for your 1978 Honda Twinstar 185, ensuring that your bike stops smoothly and safely. Whether you’re a seasoned DIYer or a beginner, this step-by-step tutorial will empower you to confidently tackle this project and keep your vintage bike in top shape.
Understanding the Brake System
Before diving into the nitty-gritty of working on your Twinstar’s brakes, it’s essential to understand how the brake system functions. The braking system of your 1978 Honda Twinstar 185 consists of several components, including the brake lever, brake cable, master cylinder, brake caliper, brake pads, and brake rotor. When you squeeze the brake lever, it activates the master cylinder, which applies hydraulic pressure to the brake caliper. The caliper then clamps the brake pads onto the rotor, creating friction and ultimately stopping the bike.
Now that you have a basic understanding of the brake system, let’s dive into the step-by-step process of working on the brakes for your 1978 Honda Twinstar 185.
Gathering the Necessary Tools and Supplies
Before starting any maintenance or repair project, it’s crucial to gather all the necessary tools and supplies. Here’s a list of items you’ll need to work on the brakes of your 1978 Honda Twinstar 185:
- Socket set
- Wrench set
- Brake cleaner
- Brake fluid
- Brake pads
- Brake rotor
- Bleeder wrench
- Brake piston tool
- Shop rag or paper towels
Ensure you have all the tools and supplies ready before proceeding with the brake maintenance.
Brake Inspection and Assessment
Before replacing any brake components, it’s essential to inspect and assess the condition of your Twinstar’s brakes. Start by visually inspecting the brake pads and rotor for any signs of wear or damage. If the brake pads are worn down beyond the recommended thickness or the rotor is warped or heavily scored, it’s time to replace them.

Replacing Brake Pads and Rotors
If your brake pads or rotor are worn out or damaged, it’s crucial to replace them to ensure optimal braking performance. Here’s a step-by-step guide to help you replace the brake pads and rotors:
Step 1: Removing the Old Brake Pads and Rotors
Start by loosening the bolts that hold the brake caliper in place using a socket or wrench. Once the bolts are loose, carefully remove the caliper from the rotor. Next, remove the old brake pads from the caliper by sliding them out. If necessary, use a brake piston tool to push the pistons back into the caliper to create enough space for the new brake pads.

Step 2: Installing the New Brake Pads and Rotors
Start by cleaning the caliper and rotor with brake cleaner to remove any dirt or debris. Once clean, insert the new brake pads into the caliper and slide them into place. Make sure they are securely seated. Next, install the new brake rotor onto the wheel hub and tighten the bolts to the manufacturer’s specified torque.

Bleeding the Brakes
After replacing the brake pads and rotors, it’s essential to bleed the brakes to remove any air bubbles that may have entered the brake lines. Here’s a step-by-step guide to bleeding the brakes:
Step 1: Preparing the Brake Bleeder
Start by locating the brake bleeder valve on the brake caliper. Attach a bleeder wrench to the valve, ensuring a secure grip. Next, place a clear tube over the bleeder valve and submerge the other end in a container filled with brake fluid. The tube will prevent air from entering the system during the bleeding process.
Step 2: Bleeding the Brakes
With the tube in place, open the bleeder valve by turning it counterclockwise with the bleeder wrench. Ask a friend to slowly squeeze and hold the brake lever while you observe the fluid flow in the tube. As your friend squeezes the lever, you may see air bubbles escaping from the tube. Once the lever is fully squeezed, close the bleeder valve by turning it clockwise with the bleeder wrench. Repeat this process until no more air bubbles are visible in the fluid and a steady stream of brake fluid flows through the tube.
