5 Essential Tips for Looking After Your Bike Brakes
Your brakes are the single most important safety system on your bike. Looking after them takes minutes and prevents the two things no rider wants: a spongy lever and a long stop. Here are the five things that matter most.
Check your brake pads for wear
Pads are consumables — they wear down every time you brake. On rim brakes, look for the wear-line grooves; if they've disappeared, replace the pads. On disc brakes, if the pad material is thinner than ~1.5mm (roughly the thickness of two coins' edges), it's time. Worn pads mean weaker braking and can score your rotor or rim.
Keep everything oil-free
Brakes work by friction, and oil kills friction. Never let chain lube, degreaser, or greasy fingers touch your pads or braking surface. If a disc rotor gets contaminated, clean it with isopropyl alcohol and a clean rag; contaminated pads usually need replacing.
Check and adjust cable tension (rim & mechanical disc)
If your lever pulls almost to the bar before biting, your cable has stretched. Most brakes have a barrel adjuster at the lever or caliper — turn it anticlockwise to take up the slack. If you run out of adjustment, the cable needs re-seating or replacing.
Keep pads aligned to the surface
Rim pads should hit the rim squarely — never the tyre (blowout risk) and never below the rim (they'll slip off). Disc pads should sit evenly either side of the rotor with no rubbing. A rubbing disc is usually a caliper alignment fix: loosen the two caliper bolts, squeeze the lever, re-tighten.
Bleed hydraulic brakes once a year
Hydraulic disc brakes feel spongy when air gets into the fluid. An annual bleed restores a firm, consistent lever. It's a straightforward job with a bleed kit, but if you're not confident, any bike shop will do it quickly — brakes are not the place to guess.
When to see a mechanic
Persistent sponginess after a bleed, a lever that pulls to the bar, uneven rotor wear, or any grinding noise. Brakes are safety-critical — when in doubt, get them checked.
Frequently asked questions
How often should I check my bike brakes?
Do a 30-second lever-and-pad check before every ride, and a proper inspection monthly.
How long do bike brake pads last?
Anywhere from 500 to 2,000+ miles depending on conditions — wet, gritty riding wears them far faster.
Can I replace brake pads myself?
Yes — pad replacement is one of the easiest home jobs. Bleeding hydraulics is the step most people hand to a shop.
