Force Hydraulic Rim Brakes [paid link] are an advanced braking system designed to deliver exceptional stopping power, modulation, and reliability for road cyclists. Whether you’re upgrading from mechanical brakes or setting up a new bike, properly installing and maintaining these brakes is crucial for optimal performance.

In this guide, we will cover step-by-step installation, fine-tuning adjustments, and essential maintenance techniques to ensure your Force Hydraulic Rim Brakes [paid link] function flawlessly.

Tools Required

Step 1: Installing the Force Hydraulic Rim Brakes

1.1 Mounting the Brake Calipers

  1. Locate the brake mounting points on your frame and fork.
  2. Using a 5mm Allen key, attach the brake calipers to the designated mounting points. Ensure the caliper arms are parallel to the rim.
  3. Tighten the bolts to the recommended torque (6-8 Nm) to secure them properly.

1.2 Connecting the Hydraulic Hose

  1. Route the hydraulic hose along the frame, securing it with cable guides or clamps.
  2. Connect the hose to the brake caliper using a T25 Torx wrench [paid link]. Ensure a snug fit but avoid overtightening.
  3. If the hose needs trimming, use a sharp hose cutter and install a new olive and insert before reconnecting.

1.3 Attaching the Brake Lever

  1. Slide the brake lever onto the handlebar, ensuring it is within reach of your fingers.
  2. Tighten the clamp bolt with a 4mm Allen key to 5-6 Nm.
  3. Align the lever angle for comfortable hand positioning.

Step 2: Adjusting the Force Hydraulic Rim Brakes

2.1 Aligning the Brake Pads

  1. Loosen the pad fixing bolts using a 4mm Allen key.
  2. Position the brake pads so they make full contact with the braking surface of the rim without touching the tire.
  3. Tighten the bolts to 4-6 Nm while holding the pads in place.

2.2 Centering the Caliper

  1. Apply the brake lever to engage the pads against the rim.
  2. While holding the lever, use a 5mm Allen key to slightly loosen the caliper bolts.
  3. Re-tighten the bolts while keeping the caliper centered.

2.3 Adjusting Lever Reach

  1. Locate the reach adjustment screw near the lever blade.
  2. Use a small Phillips screwdriver to turn the screw clockwise (to bring the lever closer) or counterclockwise (to move it farther away).

Step 3: Bleeding the Force Hydraulic Rim Brakes

3.1 Signs You Need to Bleed Your Brakes

  • The brake lever feels spongy or requires excessive travel before engaging.
  • Reduced braking power, even after pad adjustments.
  • Air bubbles in the hydraulic line.

3.2 Bleeding Process

  1. Mount the bike on a stable work stand.
  2. Remove the bleed port screw from the lever using a T25 Torx wrench [paid link].
  3. Attach the bleed syringe filled with fresh DOT 5.1 [paid link] or DOT 4 fluid.
  4. Open the bleed port at the caliper and slowly push fluid through the system.
  5. Close the caliper bleed port first, then remove the syringe from the lever.
  6. Wipe any excess fluid and replace the bleed port screw.

Step 4: Maintaining the Force Hydraulic Rim Brakes

4.1 Regular Cleaning

  • Use isopropyl alcohol and a clean rag to wipe the braking surface and calipers.
  • Avoid oil contamination on the rim or brake pads, as this reduces braking efficiency.

4.2 Checking Brake Pads for Wear

  • Inspect the pad thickness; replace if it is less than 1mm.
  • Ensure even wear on both pads. If uneven, realign the caliper.

4.3 Lubricating Moving Parts

  • Apply a small amount of mineral oil [paid link] to the brake lever pivot points to maintain smooth operation.
  • Avoid lubricating the braking surface or pads.

Frequently Asked Questions

1. How often should I bleed my Force Hydraulic Rim Brakes?

Bleed your brakes at least once a year, or whenever you notice a spongy lever feel or reduced braking performance.

2. What type of brake fluid should I use?

Force Hydraulic Rim Brakes use DOT 5.1 [paid link] or DOT 4 fluid. Do not mix with mineral oil [paid link]-based fluids, as this can damage the system.

3. How can I reduce brake noise?

Ensure your pads and rims are clean, and realign the brake caliper if necessary. If noise persists, consider using a light sandpaper to resurface the pads.

4. Why does my brake lever feel too stiff?

This could be due to overfilled brake fluid or a lack of lever lubrication. Check for fluid overflows and clean the lever pivot points.

5. Can I use Force Hydraulic Rim Brakes with carbon rims?

Yes, but you must use brake pads specifically designed for carbon rims to prevent overheating and excessive wear.

6. How do I fix uneven pad wear?

Check caliper alignment and adjust it if necessary. Also, inspect for any debris stuck in the caliper that could be causing one side to engage more than the other.

Conclusion

Installing, adjusting, and maintaining your Force Hydraulic Rim Brakes correctly ensures optimal performance and longevity. By following these steps and performing routine maintenance, you’ll enjoy consistent braking power and reliability on every ride.
