Top 10 mistakes for mounting pads, Rotors and Calipers

1 If you do not read the instructions

When fitting a new caliper, rotor or brake pad, the enclosed instruction must be followed. 

2 Not cleaning the brake pads and abutment clips

If you mount new pads where the old ones resided, you must always clean them. The slides and abutment clips should be cleaned and/or replaced. 

3 Not lubricating the guide pins

Caliper guide pins on floating calipers should be cleaned and new grease should be applied. The grease is under extreme heat and pressure, so therefore, please always use caliper specific grease. Remember to check if dust boot is torn and if so replace it. 

4 Not measuring the rotor

Rotor thickness needs to be measured every time. Running a rotor that is below specifications can cause safety issues like cracking and fading. 

5 No treatment of the rotor

New pads almost always require a fresh rotor surface so that the pads can deposit a thin layer of friction material to increase braking performance. If old, previous material is on the rotor, it can contaminate the new pad and lead to performance and noise issues.

6 Not properly torqueing the caliper bracket or guide pin bolts

Not all caliper fastening bolts are the same. Torque ranges can vary; please check the vehicle data. Furthermore, some bolts can be torque-to-yield or require liquid tread lockers. 

7 Installing a caliper upside down

Some calipers can be fitted on to opposite site. The bleeder needs to be at the top of the caliper to remove all the air. Always check the box in order to make sure, that you have a left and a right caliper before you start the job. 

8 Using cheap brake pads

We recommend, that you buy good quality in order to make sure, that you get the best result.  

9 Damaging the brake hose

Hanging the caliper by the hose while replacing rotor and pads can torn the hose. Using a clamp on the hose in order to stop the brake fluid from dripping while replacing the caliper, can cause internal damage on the hose. 

10 Not orientating the piston correctly

Please make sure, that the piston fits onto the nudge on the brake pad when replacing pad and rotor. If this is not the case, the caliper adjustment will be damaged.
