Brake liner Clarks CLARK'S 2P with Teflon 5 mm x 30 m black

Clarks CLARK'S 2P brake liner with Teflon is a continuous inner sleeve for bicycle brake housings with a 5 mm inner diameter and 30 m length in black. Designed to be inserted into standard brake outer casing, the liner provides a low-friction Teflon-coated surface that reduces cable drag and minimizes internal wear. It is suitable for building new brake runs, replacing worn liners, or creating custom-length housings for rim and mechanical disc brake systems where a smooth cable action is required.

Advantages

The Teflon coating on the inner surface lowers friction between the cable and housing, resulting in smoother lever feel and reduced cable wear. The 5 mm diameter is compatible with standard brake cables and the long 30 m spool allows multiple repairs or custom-length housing assemblies without splicing. The black finish offers a discreet appearance inside the outer casing and the continuous sleeve form simplifies installation compared with segmented liners.

Suitable for

• Replacing worn or damaged brake liner inside existing brake outer casing
• Building or cutting continuous brake housing lengths for bicycles
• Long cable runs where reduced friction improves braking response
• Repair workshops and DIY bicycle maintenance projects

Key specifications

• Inner diameter: 5 mm suitable for standard brake cables
• Length: 30 meters continuous sleeve
• Inner surface: Teflon-coated low-friction lining
• Color: black
• Form factor: continuous flexible liner for insertion into brake outer casing

How to use

Cut the liner to the required length using a sharp cutter or scissors, taking care to leave enough allowance for end fittings. Insert the liner into the outer brake casing so it runs the full length between lever and brake caliper. Feed the brake cable through the liner, then fit the usual ferrules and end caps to the outer casing. Check for smooth cable movement and, if necessary, trim any uneven edges at the ends before final assembly.

Usage recommendations

For optimal performance, ensure the liner is fully seated inside the outer casing and that ferrules are correctly fitted to prevent the liner from bunching. Replace the liner if cuts, severe kinks, or contamination are present. When cutting the liner, use a sharp tool for a clean edge to maintain smooth cable movement.
