Adjusting Pad Gap and Cable Tension

Why 1.5 mm is the magic number, and how the barrel adjuster works.

Pad gap and cable tension are the same system. Get the gap right and the lever feels perfect. Here it is, frame by frame.

Pro tip
Use the Play button to watch the sequence, or step through with the arrows. Each frame is one real action.

Why this works

V-brakes are simple levers. The pad gap, the cable tension, and the toe-in angle are the three things that decide whether your brake is silent, firm, and safe. Get those right and almost every fault disappears.

⚠
Ride-safe reminder. After any brake work, test in a safe area. If the wheel won't stop or the lever reaches the bar, don't ride — re-check the gap and cable, or visit a shop.
