Routine maintenance and repairs26 27Pre-ride quick check

A quick check-over before any ride is always a good idea. Concentrate on the safety-critical items before looking at the drivetrain and comfort items. After all, a loose bottle cage, whilst inconvenient, won t be a disaster, but a loose wheel will! None of the checks (apart from tyre pressures) require any tools, but it may be worth having a multi-tool in your pocket in case any adjustment or tightening is required.

Pre-ride quick check

1Check the security of the wheels in the drop outs.

9Check for loose or damaged spokes.

5Check the rim baking surface for wear and damage. This rim has seen better days.

13Check the security of the handlebars. Hold the wheel and try to turn the bars.

17Check the tyre pressures.

2Grasp the front wheel at the rim and rock it from side to side to check for play in the bearings. Lift the wheel and spin it. Listen for the noise of worn or damaged bearings.

10Check the brake cables for damage and wear to the outer cable. This inner cable requires immediate replacement.

6Check that the pads meet the rim correctly.

14Grasp the saddle and check that it s secure.

18Grab the cranks and push them in and out to check for play.

21Check the rear derailleur for alignment and worn jockey wheels. This jockey wheel requires immediate replacement.

3Do the same for the rear wheel. A small amount of play is acceptable.

11On bikes with hydraulic brakes check the hose for chafing. Pay particular attention to anywhere that the hose is clamped to the frame or the forks.

7On bikes with disk brakes check the pads for wear.

15Check the tyre sidewalls for damage. This tyre needs replacing.

19Check the chainrings for worn and damaged teeth. This chainring has a broken tooth.

22On bikes with front suspension, check for oil leaks and wear. Oil is starting to leak from this front suspension fork.

4Check the brake pads for wear.

12Pull on the front brake and rock the bike back and forth to check for play in the headset bearings.

8Check the security of the rotor.

16Check the tyre treads for wear and foreign objects.

20Check the rear sprockets or cassette for wear and damage.

23On full suspension bikes check for wear in the pivots.

Braking systems54 55Cable disc brakes

Now available on many bikes, the development of disc brakes has progressed in leaps and bounds. Available as simple cable-operated models through to four (or more) cylinder, hydraulically operated downhill monster brakes, they can have simple solid rotors, floating rotors and even vented rotors. Cable-operated disk brakes offer powerful and consistent braking in all conditions. On a commuter bike they re perfect, as they re not affected by a buckled or damaged rim. They re also becoming popular on touring bikes as there s no rim wear, and when used on the road the brake pads will last for many thousands of miles. This will, of course, depend on your riding style and the weather conditions. Hydraulically-operated disc brakes have several advantages over cable-operated types. The fluid hose can be routed around complex suspension frames with no loss of braking power, and there s no cable to seize up and create extra drag. Most modern designs are also self-adjusting. The installation, checking, bleeding and replacement of hydraulic brakes is covered on pages 64 65. For both cable and hydraulic brakes it s important that the spokes, hub and rim are all in good condition. A wheel that s out of true or has some minor rim damage will not be an issue. However, the braking force generated at the rotor has to be transmitted to the tyre via the hub, spokes, rim and tyre, and this force is considerable, so missing or damaged spokes could lead to failure of the wheel.

Disc brake mounts Disc brakes are mounted using either the International Standard (IS) mounting system or the Post Mount (PM) system. Some early versions used a manufacturer-specific mounting, but these are now rare. The PM mounting is becoming increasingly popular, as it offers easy caliper alignment and reduces manufacturing costs. However, it relies on mounting hardware that s retained by a threaded hole in the frame or fork, and any damage to these threads may write off the bike. Fortunately once the mounting adapter has been fitted there s little need to remove it. The mounting bolts should, of course, be checked at every service.

Cable disc brakes

IS standard discs (or rotors) are held in place with six bolts.

A typical post-mount adapter and hydraulic brake.

Shimano s centre lock system uses a single fixing that requires a special tool to install the disc. This is the same tool used for rear free hub cassettes.

Different brake adapters will be required to suit the various mounting systems, disc sizes

and calipers.

AdjustiNg CABle disC BRAke PAds The exact method of adjustment will depend on the model of brake fitted. The brake shown in the sequence above requires an 8mm spanner to undo the lock nut. With the lock nut freed off, use a 2.5mm hex key to adjust the brake-pad clearance on the rotor. Operate the brake a few times and readjust the clearance if necessary. Counter-hold the 2.5mm hex key and tighten the 8mm lock nut when you re happy with the operation of the brake. Note that it s perfectly normal to feel a slight drag from the pads as the wheel is rotated.

Cable disc brakes: checking and adjustment

1Open the quick release and gently pull the wheel free, taking care not to damage the brake rotor. It may be necessary to back off the brake pads to allow the wheel to be removed cleanly.

5Tap or pick out the old pad. Inspect it for wear and clean the pad housing with a specialist brake cleaner.

2On this style of cable-operated disc brake you ll need to use a spanner to counter-hold the cable locking bolt in order to remove the cable. This needs to be done whenever the brake pads are removed and replaced.

6Apply a tiny amount of copper-based anti-seize compound to the rear of the new pads and fit them into the caliper, taking care to align them properly.

3To replace the pads on this brake you must release the three bolts and split the caliper into two parts. Slacken each bolt evenly to avoid any distortion to the caliper.

7Refit the caliper complete with the new brake pads, and then refit the three mounting bolts, tightening them evenly and in diagonal sequence.

4With the caliper split into two, lever free the brake pad spring, taking care not to lose or distort it.

8Before refitting the wheel check that the caliper moves freely on the sprung mountings. If necessary carefully lubricate the sliding pivots. Refit the front wheel and adjust the brake-pad clearance.

WHeN YOu Need tO dO tHis: m It s worth stripping out the pads every six months or so to

check that they re not excessively worn. m When the pads are worn and brake lever travel is excessive.

tiMe: m This will depend on how the pads are retained in the

caliper. Some pads are easy to change in a matter of minutes, others that require the caliper to be stripped apart can take an hour or so.

diFFiCultY:JJ m A straightforward job. The only problem you re likely to

encounter is adjusting the position of the pads in the caliper.
