Pro tips
·

The barrel adjuster is your friend. Turn it anti-clockwise (out) to tighten the cable and bring pads closer to the rim. Quarter turns at a time.

·

On a fixie like the SE Lager, your front brake is your only brake (plus leg resistance). Keep it in perfect condition — it's all you've got.

·

Brake pads have wear lines. If the grooves have disappeared, replace them immediately.

·

Toe-in your brake pads slightly (front of pad touches rim first) to eliminate squealing.

Step by step
01

Spin the wheel. Check if pads are rubbing — if so, the caliper needs centring

02

CABLE TENSION: Turn barrel adjuster anti-clockwise ¼ turn at a time until brake bites firmly at half-lever pull

03

If the barrel adjuster runs out of adjustment, you need to pull slack through the cable clamp bolt

04

CENTRING (rim brakes): Loosen the caliper mounting bolt slightly. Squeeze the brake, hold it, re-tighten the bolt

05

Check pad alignment — pads should hit the rim squarely, not touching the tyre

06

For toe-in: bend the pad holder slightly so the front of the pad contacts the rim first

07

DISC BRAKES: Check pad thickness through the caliper window. Replace if less than 1mm of material

08

Test ride: brake firmly from moderate speed. Both brakes should stop you smoothly without pulling to one side
