The Level TL [paid link] disc brakes are a mid-range hydraulic braking system from SRAM, designed for precise modulation and strong stopping power on road and mountain bikes. Whether you are installing new brakes, adjusting the calipers, or maintaining the system for long-term reliability, this guide will cover every aspect of working with SRAM Level TL [paid link] disc brakes.

By following this detailed guide, you will learn how to:

• Properly install the Level TL [paid link] brake system
• Adjust the calipers and levers for optimal braking performance
• Perform routine maintenance to keep your brakes in top condition
• Troubleshoot common braking issues

Tools Required

To install, adjust, and maintain your Level [paid link] TL disc brakes, you will need the following tools:

• T25 Torx wrench [paid link]
• 5mm Allen wrench [paid link]
• Torque wrench [paid link]
• DOT 5.1 [paid link] brake fluid (for hydraulic bleeding)
• Bleed kit [paid link] (includes syringes and fittings)
• Isopropyl alcohol and clean rags
• Rotor truing tool (if necessary)

Installation Guide for Level TL Disc Brakes

1. Preparing Your Bike

Before installing your Level [paid link] TL brakes, ensure your bike is clean and ready:

• Remove your existing brakes if replacing them.
• Check the frame and fork for flat-mount or post-mount compatibility.
• Ensure your wheels are fitted with compatible 6-bolt or CenterLock rotors.

2. Installing the Brake Calipers

1. Attach the caliper to the frame or fork using the appropriate bolts.
2. Lightly tighten the bolts (do not fully torque yet).
3. If using a post-mount system, install the correct adapter based on rotor size.

3. Mounting the Brake Levers

1. Slide the Level [paid link] TL brake levers onto the handlebars.
2. Position them at a comfortable angle for your hand position.
3. Tighten the clamps using a 5mm Allen wrench [paid link], ensuring they are secure but adjustable.

4. Installing the Rotors

1. If using 6-bolt rotors, attach them to the hub using a T25 Torx wrench [paid link] and tighten to the manufacturer’s torque spec.
2. If using CenterLock rotors, secure them with the lockring and tighten using a cassette lockring tool [paid link].

5. Connecting the Brake Hoses

1. Route the hydraulic hose from the caliper to the brake lever.
2. Trim the hose to the correct length using a sharp cutter.
3. Insert an olive and barb into the hose and attach it to the lever.
4. Secure the connection by tightening the compression nut.

6. Bleeding the Brakes

Since Level TL disc brakes are hydraulic, proper bleeding is essential:

1. Fill the bleed syringes with DOT 5.1 [paid link] brake fluid.
2. Attach the syringes to the caliper and lever bleed ports.
3. Push fluid through the system to remove air bubbles.
4. Close the ports and clean excess fluid with isopropyl alcohol.

Adjusting Level TL Disc Brakes

1. Centering the Brake Calipers

1. Loosen the caliper mounting bolts slightly.
2. Squeeze the brake lever firmly and hold it.
3. While holding the lever, tighten the caliper bolts evenly.
4. Release the lever and check for rotor rub. Adjust if necessary.

2. Adjusting Lever Reach

The Level TL levers feature a reach adjustment dial:

1. Turn the reach adjust screw near the lever pivot using a 2.5mm Allen wrench [paid link].
2. Rotate clockwise to bring the lever closer or counterclockwise to move it away.

Maintenance for Level TL Disc Brakes

1. Cleaning the Brake Rotors

• Use isopropyl alcohol and a clean rag to wipe down the rotors.
• Avoid using oily or contaminated rags that may cause brake squeal.

2. Checking Brake Pad Wear

• Remove the wheel and inspect the brake pads for thickness.
• If the pads are less than 1mm thick, replace them immediately.

3. Inspecting for Leaks

• Check the brake hose connections at the caliper and lever for any fluid leaks.
• Tighten any loose fittings and replace damaged hoses.

4. Bleeding the Brakes Regularly

• Hydraulic brakes should be bled once a year or if the brake feel becomes spongy.
• Follow the bleeding process outlined earlier for proper fluid replacement.

Troubleshooting Common Issues

1. Brakes Feel Spongy

• Solution: Bleed the system to remove air bubbles.
• Check: If fluid leaks are present, replace worn seals.

2. Brake Pads Rubbing on the Rotor

• Solution: Recenter the caliper using the steps in the Adjustment section.
• Check: Ensure the rotor is straight; use a rotor truing tool if necessary.

3. Brakes Are Noisy or Squealing

• Solution: Clean the rotor and brake pads with isopropyl alcohol.
• Check: Ensure pads are properly bedded in.

4. Weak Braking Power

• Solution: Replace worn brake pads and bleed the system.
• Check: Use the correct brake rotor size for your riding style.
