Magura’s MT7 Pro [paid link] brake sets are known for their exceptional stopping power and performance, making them a popular choice among serious cyclists. However, like all hydraulic disc brakes, they require occasional maintenance to ensure optimal performance. One of the most essential maintenance tasks for your MT7 Pro brake set is bleeding the brakes. This procedure removes air from the brake lines and ensures that the hydraulic fluid flows freely, providing consistent braking performance.

Tools Required

  • Magura MT7 Pro brake bleed kit
  • 7mm wrench
  • 2.5mm and 3mm Allen wrenches [paid link]
  • T10 Torx wrench
  • Bleed block
  • Small container for fluid
  • Magura Royal Blood brake fluid
  • Syringe with tubing
  • Isopropyl alcohol
  • Lint-free cloth
  • Gloves and safety glasses

Preparation for Bleeding the MT7 Pro Brakes

Before starting the bleeding process, gather all necessary tools and materials. Ensuring everything is at hand will make the process smoother and reduce the chances of interruptions. Always work in a well-lit, clean, and ventilated area, as brake fluid can be hazardous if not handled properly.

Step 1: Remove the Wheel

Start by removing the wheel to expose the brake calipers. This gives you easy access to the brake components and reduces the risk of accidentally damaging the wheel or rotor during the bleeding process.

Step 2: Insert the Bleed Block

Insert a bleed block into the brake caliper. This will protect the brake pads from being pressed together during the process, which could damage them. The bleed block also ensures that the brake pistons remain properly aligned and don’t retract into the caliper, which can complicate the bleeding process.

Step 3: Set Up Your Workspace

Place a small container beneath the brake caliper to catch any fluid that may spill during the bleeding process. It’s important to work with care since brake fluid can damage paint and other surfaces.

Performing the Bleed

With your tools ready and your bike prepared, you can now begin the bleeding process. Follow these steps carefully to ensure a proper and effective bleed.

Step 4: Remove the Brake Lever Reservoir Cap

Using the 7mm wrench, remove the reservoir cap on the brake lever. Make sure to clean the area around the cap to prevent dirt or debris from contaminating the brake fluid.

Step 5: Attach the Syringe to the Brake Lever

Attach the syringe filled with Magura Royal Blood brake fluid to the brake lever’s reservoir port. This will allow you to push fluid into the brake system. Be sure to use the appropriate tubing to connect the syringe securely to the port.

Step 6: Open the Bleed Port on the Caliper

Using the 2.5mm Allen wrench, remove the bleed port screw on the caliper. This will allow brake fluid to flow out of the caliper as air is pushed out of the system.

Step 7: Push Fluid into the System

Slowly depress the syringe plunger to force brake fluid into the system. You should notice fluid beginning to flow from the bleed port on the caliper. Continue applying fluid until the syringe empties and you see clean fluid, free from air bubbles, flowing out of the caliper.

Step 8: Close the Bleed Port on the Caliper

Once the fluid runs clear without bubbles, use your 2.5mm Allen wrench to securely tighten the bleed port screw. This ensures that no air or fluid can escape once you finish the process.

Step 9: Remove the Syringe

After the fluid has been pushed through and the bleed port is sealed, carefully remove the syringe from the brake lever’s reservoir port. Be cautious not to spill any fluid as you do this.

Step 10: Fill and Seal the Brake Lever Reservoir

Replenish the brake fluid in the brake lever’s reservoir if necessary. Add fluid to the reservoir until it reaches the recommended level, making sure the fluid is clean and free from air. Once you’ve filled the reservoir, replace the reservoir cap and tighten it with the 7mm wrench.

Step 11: Test the Brake Lever

Before reassembling the bike, test the brake lever by pressing it to ensure it feels firm and responsive. If the lever pulls in too easily, air may still be present in the system. Repeat the bleeding procedure if necessary.

Post-Bleeding Maintenance

After successfully bleeding your MT7 Pro brake set, it’s essential to perform some post-maintenance checks.

Step 12: Reinstall the Wheel

Once you’re confident that the brakes are functioning correctly, reinstall the wheel onto the bike. Check that the rotor is properly aligned and doesn’t rub against the brake pads.

Step 13: Test Ride

Finally, take the bike for a short test ride to ensure that the brakes are performing correctly. During the ride, test the braking power and lever feel. If any issues arise, repeat the bleeding process or check for possible leaks in the brake system.

Troubleshooting Common Brake Bleeding Issues

Despite your best efforts, you may encounter issues during or after bleeding your MT7 Pro brakes. Here are some common problems and how to address them.

Air Bubbles in the System

If air bubbles remain in the brake fluid after bleeding, the brake lever may feel spongy or soft. To resolve this, ensure the syringe is fully seated and there are no leaks. Try the bleeding procedure again, paying extra attention to the fluid flow.

Insufficient Brake Power

If the brakes feel weak or ineffective after bleeding, check for potential issues with the brake pads or caliper alignment. Make sure the brake pads are properly installed and that the caliper is aligned with the rotor. If needed, inspect the hydraulic system for leaks.

Fluid Leaks

If you notice fluid leaking around the bleed port or reservoir, ensure that all screws and fittings are tightened properly. It may also be necessary to replace seals or o-rings if they have worn out over time.

Customization and Optimization for Better Performance

Magura’s MT7 Pro brake sets are highly adjustable and offer options for further customization. Here are some tips for optimizing your brake set:

  • Brake Lever Reach Adjustment: The MT7 Pro levers come with a reach adjustment feature, allowing you to fine-tune the distance between the lever and handlebar. This can improve comfort and control, especially during long rides.
  • Pad Material Selection: Consider switching to sintered brake pads if you ride in wet or muddy conditions. These pads offer better performance and durability compared to organic pads, especially under harsh riding conditions.
  • Rotor Size: If you feel that your brakes could use more stopping power, upgrading to larger rotors can increase braking performance. Ensure that your bike’s frame and fork are compatible with larger rotors before making the switch.

Comparison with Other Hydraulic Brake Models

When comparing the Magura MT7 Pro to other hydraulic disc brake systems, the MT7 Pro stands out due to its superior stopping power, customizable features, and lightweight design. Models like the Shimano XT or SRAM Guide also offer high performance, but the MT7 Pro’s adjustable lever and solid braking force make it ideal for aggressive riders and downhill enthusiasts.

Compatibility with Other Drivetrain Components

The MT7 Pro brake set is compatible with a wide range of drivetrain components, including Shimano, SRAM, and Campagnolo systems. However, it’s important to ensure that the brake rotor size and adapter match your bike’s frame and fork specifications. The MT7 Pro can be used with different rotor sizes (up to 220mm), offering flexibility depending on your riding style.

The Magura MT7 Pro brake set delivers exceptional performance when properly maintained. Following these steps for bleeding, troubleshooting, and optimization will help keep your brakes in top condition, ensuring safety and efficiency on every ride.
