Understanding Your Shimano MT200 Hydraulic Disc Brakes

Before diving into maintenance and troubleshooting, it’s helpful to understand the basic anatomy of your Shimano MT200 hydraulic disc brake system. These brakes utilize a hydraulic fluid to transfer force from the brake lever to the brake caliper, squeezing the brake pads against the rotor. This system offers superior stopping power and modulation compared to traditional cable-actuated rim brakes. The core components include:

• Brake Levers: These are what you squeeze to engage the brakes. The MT200 levers are designed for comfort and a firm grip.
• Brake Hoses: These are the lines that carry the hydraulic fluid from the levers to the calipers.
• Calipers: Mounted on the frame or fork, these house the brake pads and pistons. When you pull the lever, the pistons push the pads against the rotor.
• Brake Pads: These are the friction material that contacts the rotor. They are wear items and will need replacement over time.
• Rotors: These metal discs attach to your wheel hubs and are what the brake pads clamp onto.
• Hydraulic Fluid: Shimano uses mineral oil for its hydraulic brake systems. This fluid is essential for transferring force and needs to be kept clean.

Understanding these parts will make subsequent steps much clearer. Think of the system like a miniature circulatory system for your bike, where the fluid is the blood, carrying the command to stop from your fingers to your wheels.

Installing Your Shimano MT200 Hydraulic Disc Brakes: A Step-by-Step Approach

Installing hydraulic disc brakes can seem intimidating, but with patience and the right tools, it’s a manageable task. This guide assumes you’ve purchased the brakes as a complete kit, which typically includes levers, hoses, and calipers. Always refer to the official Shimano service manual for the most precise instructions, as it provides detailed diagrams and specifications.

Step 1: Mounting the Calipers

First, you’ll need to mount the brake calipers to your bike’s frame and fork. Most modern bikes are equipped with Post Mount or Flat Mount tabs for disc brake calipers. The MT200 calipers typically use Post Mounts.

1. Identify Mount Type: Ensure your frame and fork have the correct disc brake mounts.
2. Position the Caliper: Place the caliper over the mounting bolts. For Post Mounts, the caliper straddles the mounting bolts that thread directly into the frame/fork.
3. Install Mounting Bolts: Insert the mounting bolts through the caliper and into the frame/fork. Do NOT tighten them fully yet.
4. Align the Caliper: Squeeze the corresponding brake lever firmly. While holding the lever, tighten the mounting bolts. This action centers the caliper over the rotor, ensuring no rubbing.
5. Check for Clearance: Release the lever. The rotor should spin freely without contacting the brake pads. If it rubs, slightly loosen the mounting bolts, adjust the caliper position, and re-tighten.
6. Torque Bolts: Once aligned, tighten the mounting bolts to the manufacturer’s recommended torque (usually around 6-8 Nm).

Step 2: Attaching the Brake Levers and Hoses

This step involves mounting the levers onto your handlebars and connecting them to the calipers via the brake hoses.

1. Position Levers: Slide the brake levers onto the handlebar in your preferred position. Ensure they are oriented for comfortable reach and operation.
2. Tighten Lever Clamp: Tighten the clamp bolts to secure the levers, but not so tight that you can’t make fine adjustments later.
3. Route Hoses: Carefully route the brake hoses along your frame and fork. Use zip ties or integrated frame routing ports to keep them tidy and prevent snagging. Avoid sharp bends or kinks in the hose, as this can impede fluid flow.

Step 3: Bleeding the Brakes (If Necessary)

New systems usually come pre-bled, but if you’ve cut hoses or the system feels spongy, you’ll need to bleed it. Bleeding removes air bubbles from the hydraulic system, ensuring optimal performance. You will need a Shimano bleed kit for this.

1. Gather Supplies: You’ll need the Shimano bleed kit, Shimano mineral oil, clean rags, and possibly new hose seals and olives.
2. Prepare the System: Remove the wheel and place the caliper on a stand or support. Attach the bleed funnel to the lever’s reservoir port and fill it with mineral oil.
3. Attach Syringe to Caliper: Remove the bleed screw from the caliper and attach the filled syringe from the bleed kit.
4. Push Oil Through: Slowly push the oil from the syringe up through the caliper and into the hose and lever reservoir. You’ll see air bubbles rise into the funnel.
5. Work the Lever: While oil is flowing, gently pump the brake lever a few times to help dislodge any trapped air.
6. Close Bleed Port: Once no more air bubbles are visible, close the bleed screw on the caliper while the syringe is still attached and under pressure.
7. Remove Syringe and Funnel: Remove the syringe and then the funnel. Clean up any spilled oil.
8. Refill Reservoir: Top off the lever reservoir with mineral oil and replace the reservoir cap.
9. Test Lever Feel: The brake lever should now feel firm and responsive.

Pro Tip: Always use genuine Shimano mineral oil. Using other types of hydraulic fluid can damage your brake system.

Essential Maintenance for Your Shimano MT200 Brakes

Regular maintenance is key to ensuring your Shimano MT200 hydraulic disc brakes perform reliably and last longer. Here’s a breakdown of what you should be doing:

Regular Cleaning

Keep your brakes clean, especially the rotors and pads. After muddy or wet rides, rinse your bike and use a mild soap and water to clean the rotors and calipers. Avoid getting degreaser directly on the rotors or pads, as this can contaminate them and reduce braking performance.

Pad Inspection and Replacement

Brake pads wear down over time. Inspect them regularly. Most pads have a minimum thickness indicator. When they reach this point, or if they start to squeal excessively, it’s time to replace them.

• Remove Wheel: Take the wheel off the bike.
• Remove Pads: They are usually held in place by a small pin or clip. Remove this, and the pads should slide out.
• Inspect Wear: Check the thickness of the friction material.
• Install New Pads: Slide the new pads into the caliper.
• Reinstall Pin/Clip: Secure the new pads with their retaining pin or clip.
• Bed In New Pads: New pads need to be “bedded in” to achieve full braking power. Ride your bike and apply the brakes firmly from medium speed (e.g., 15 mph) down to a slow speed, without coming to a complete stop. Repeat this 10-20 times for each brake.

Rotor Care

Rotors should be kept clean and free from damage. Inspect them for any bends or deep scratches. If a rotor is significantly bent, it may need to be trued or replaced. Clean rotors with isopropyl alcohol on a clean rag to remove any film or contamination.

Checking for Leaks

Periodically inspect the brake hoses and around the caliper and lever for any signs of hydraulic fluid leaks. If you see oily residue, it might indicate a loose fitting or a damaged hose, and your brakes may need professional attention.

Lever Feel

Pay attention to how your brake levers feel. If they start to feel “spongy” or can be pulled all the way to the handlebar without strong braking action, it’s a sign that there might be air in the system or the fluid needs to be changed. This is when bleeding the brakes becomes necessary.

Troubleshooting Common Shimano MT200 Brake Issues

Even with the best maintenance, you might encounter a few common issues with your Shimano MT200 hydraulic disc brakes. Here’s how to address them:

Spongy Brake Lever

Cause: Air in the hydraulic system. This is the most common cause for a spongy lever feel.

Solution: Bleed the brake system as described in the installation section. Ensure you use the correct Shimano mineral oil and follow the bleeding procedure carefully.

Brakes Rubbing Constantly

Cause: Misaligned caliper or warped rotor. The pads might be too close to the rotor.

Solution:

1. First, try centering the caliper by loosening the mounting bolts, squeezing the brake lever, and re-tightening the bolts while holding the lever.
2. If rubbing persists, check if the rotor is bent. You can sometimes straighten a slightly bent rotor with a rotor truing tool. If it’s badly damaged, it needs replacement.
3. Ensure the brake pads are properly seated in the caliper.

Squealing or Grinding Noises

Cause: Contaminated brake pads, worn-out pads, or glazed rotor surface.

Solution:

1. Contamination: Clean the rotors with isopropyl alcohol. If pads are contaminated, they might need to be replaced.
2. Worn Pads: Inspect and replace worn brake pads.
3. Glazed Rotor: Lightly sand the rotor surface with fine-grit sandpaper and clean thoroughly.
4. Alignment: Ensure the caliper is perfectly aligned. Sometimes, slight misalignment can cause noise.

Brakes Not Stopping Effectively

Cause: Worn pads, contaminated pads, air in the system, or oily rotors.

Solution:

1. Inspect and replace worn brake pads.
2. Clean rotors and replace contaminated pads.
3. Bleed the brake system if it feels spongy.
4. Ensure rotors are clean and free of any lubricants.
5. Check that the brake pads are compatible with your rotors (resin vs. metallic).
