Bike Brake Repair London: Squeaking, Rubbing & Spongy Brakes Fixed

Brakes are the one part of your bike you cannot afford to get wrong. If yours are squeaking, rubbing, grinding or the lever is pulling all the way to the bar, something needs looking at, and usually it is a quick, inexpensive job.

The short answer: most brake problems come down to worn pads, contaminated pads or discs, a misaligned calliper or air in a hydraulic system. At NipNip, brake pads are fitted from £16 per brake, a brake adjustment is £16 and a hydraulic disc bleed is £26 per brake, with parts extra. Prices can vary by location.

If your brakes feel weak or the lever reaches the handlebar, stop riding and bring the bike in. Book a brake repair or walk in at one of our London workshops.

What is your brake doing?

Squeaking or squealing

The most common brake complaint we see. Likely causes:

• Contaminated pads or rotors. Oil, chain lube or road grime on a disc brake causes a loud howl and a big drop in stopping power.
• Glazed or worn pads. Pads that have overheated or worn thin can squeal and stop poorly.
• Calliper alignment. A calliper that is slightly out can vibrate and sing.

Contaminated pads usually cannot be cleaned reliably and need replacing. Wet London weather makes this worse through the winter.

Grinding or metal-on-metal

If you hear grinding, the pads may have worn through to the backing plate. This damages rims or rotors quickly and turns a £16 pad job into a new rotor or wheel. Get it checked straight away.

Rubbing on the wheel

A brake that rubs slows you down and wears the pads. It is usually a misaligned calliper, a slightly buckled wheel or a wheel not seated properly in the dropouts. A brake adjustment (£16) often sorts it, and we will tell you if the wheel needs truing.

Spongy lever or lever hitting the bar

On hydraulic disc brakes, a soft lever often means air in the system or a leak. On rim and mechanical disc brakes it usually means stretched cables or worn pads. Either way, this is a safety issue. A disc brake bleed is £26 per brake; mechanical brakes may need new cables from £16.

Weak braking in the wet

Some loss of power in the rain is normal on rim brakes, but if you are struggling to stop, your pads are likely worn or hardened. Fresh pads make a huge difference on London's wet winter roads.

Is it safe to ride with squeaky brakes?

A squeak on its own is not always dangerous, but it is often the first sign of contamination or worn pads, both of which reduce stopping power. If the noise comes with weaker braking, grinding or a lever that pulls further than usual, stop riding and get it checked.

How often should brake pads be replaced?

It depends on mileage, weather and riding style. A daily London commuter riding through winter can wear through disc pads in a few months. As a rule, if the pad material is thinner than about 1.5mm, it is time for new ones.
