FORM ENDURANCEAcademyKnow your components · 12 MIN
Inspect the right parts for your brake system and recognise service needs.
Front and rear: brake type unknown. Identify both brakes; a visible cable alone does not rule out a hydraulic hybrid caliper.
Actuation. Cable, hydraulic or a combination. Identification comes before adjustment.

STEP 1 OF 5
Your selection: unidentified brake. Trace the control to the brake and find the model code before using any model-specific limit or adjustment.
Disc pads act on a rotor attached to the hub. Cable and hydraulic calipers can look similar from a distance; inspect the input and identify the model.
The selected brake agrees with the actual component. If uncertain, return to identification.
Inspection with the wheel installed. Adjustment, pad replacement, rotor truing and bleeding are separate model-specific procedures.
Source check: September 2026. Use the current manual for your exact component. These lessons do not replace model-specific service instructions.
Your selection: unidentified brake. Trace the control to the brake and find the model code before using any model-specific limit or adjustment.
Disc pads act on a rotor attached to the hub. Cable and hydraulic calipers can look similar from a distance; inspect the input and identify the model.
What you’re checking: The selected brake agrees with the actual component. If uncertain, return to identification.
Allow the brake to cool after riding. Keep fingers away from rotor openings and spokes. Do not touch the braking surface with oily hands.
Keep oil and lubricant off pads and rotors. Leave the wheel installed. On hydraulic systems, operating the lever with the wheel out and no correct spacer can move the pistons too far.
What you’re checking: The brake is cool, the wheel is installed and friction surfaces are uncontaminated.
Locate the brake’s model code and confirm how it operates. Learn the parts in the example, but do not transfer an adjustment or wear limit to an unidentified brake. A bicycle shop can identify it.
Check the opposite brake too: the front and rear may have different components. Change the Front / Rear selector to use the matching lesson view.
What you’re checking: No leak, damaged cable, crack or unexplained change remains unaddressed.
Distinguish the friction material from its metal backing plate. Manufacturers may specify friction thickness or total pad thickness; those are different measurements. Use the method and limit for your exact pad and brake.
The rotor has its own model-specific minimum thickness and inspection method. The demonstration enlarges the parts to show their relationship; it is not a measuring scale. If pad access requires removal, use the correct service procedure or a mechanic.
What you’re checking: You know which wear indicator or measurement applies. You have not substituted a generic number.
With the bike stationary and the wheels installed, operate each brake and check for normal feel, return and security. A lever reaching the handlebar, unexpected loss of force, damage or leakage means stop using the bike and arrange service.
Only after stationary checks pass, check both brakes at low speed in a clear, level area following the bicycle manual. If performance is uncertain, stop. Do not choose a bleed fluid by brand or perform an adjustment to hide an unexplained fault.
What you’re checking: Both brakes perform normally; every failed or uncertain check is resolved before riding.
