Adjusting the brake lever reach

With disc brakes the brake levers can be adjusted to 

the size of your hands, too, allowing you to operate 

them with optimal effectiveness 

(a-c)

.

 

For more information see the chapter “Adjusting the 

brake lever reach on CENTURION road bikes” and in 

the original operating instructions of the brake manu-

facturer on this CENTURION CD-ROM.

After adjusting check the functioning and make sure 

the brake pads do not drag when releasing the brake 

lever and spinning the wheel.

Checking and readjusting in the case of me-

chanical disc brakes

Regularly check the braking response and the con-

dition of the brake cables while pulling on the brake 

lever.

Do you get a clear-cut braking response when you 

pull the brake lever hard, and does the lever remain 

clear of the handlebars no matter how hard you pull?

To a certain extent, an increasing lever travel due 

to wear of the brake pads can be compensated at 

the additional brake lever’s adjusting element on the 

brake cable or directly at the brake caliper. 

Unscrew the union nut on the bolt through which 

the cable enters the brake caliper

 (d) 

and then un-

screw the bolt until the lever has the desired travel. 

Retighten the lock nut by taking care that the slit of 

the screw head does not face forward, as this would 

unnecessarily permit water or dirt to enter. There are 

some models which require an additional adjustment 

directly inside the brake caliper.

Check at regular intervals, whether the brake pads 

are still sufficiently thick. The wear of the pads can 

be checked at the inspection window on the upper 

side of the brake caliper. If there is approximately  

1 mm of material left on each brake pad, remove the 

pads according to the manufacturer’s operating in-

structions, check them thoroughly and replace them, 

if necessary.

After readjusting check the functioning and make 

sure the brake pads do not drag when releasing the 

brake lever and spinning the wheel.

Repeated readjustment at the brake lever makes the 

arm on the brake caliper change its position. This can 

make the brake less effective and result in a complete 

brake failure in an extreme case. Risk of an accident!

Some models offer further ways of adjusting the 

brakes directly at the brake caliper, though this re-

quires a certain amount of skill. Ask your CENTURION 

dealer for advice.
