Fitting Brake Pads
Swap your pads over for something a bit better.
Here I will be fitting RedDot brake pads that match the RedDot brake discs.
Matching brake components is quite important for safety and brake life.
With the car jacked up and the wheel removed, undo the top caliper bolt
using a 13mm spanner on one side and a 17mm spanner on the other.
With the bolt out, the centre section of the caliper will be loose.
Swing the caliper down, the pads will stay in place. Support the weight
of the caliper, don't let it hang from the brake pipe as it can damage it.
The pads can be removed from the caliper cage.
Open up the offside service hatch and open the cap of the brake reservoir.
The piston will now quite easy to push back in to make room for the new pads.
When you place the new pads into the caliper cage, pay attention to the pad with the metal tab attached. These pads go on the inside, the plain pads go on the outside.
Info: The tab is an acoustic wear indicator. When the pad gets too thin, the
metal tab touches the brake disc and makes a terrible noise when you brake.
The metal tabs are circled in red to show the orientation relative to the caliper.
Here is a detailed picture of one of the pads, you will notice that each pad has a spring attached to the top. These press against the caliper to hold them in place.
An INCORRECTLY fitted set of pad springs will protrude from the calipers as seen below.
In these circumstances the pads may rattle or click during use.
Ensure both anti-rattle springs are level as the caliper is folded back in place.
You will see through the viewing window that the springs are correctly positioned
plus you will feel the springs pushing on the caliper as you close it up.
Do the 13mm caliper carrier bolts up tight, you may need to hold the
other side of the bolt receiver with a 17mm spanner to stop it spinning.
Replace the wheel, retighten the brake reservoir cap and pump the brake pedal.
Bedding In The New Brakes
Considering the discs and pads are from RedDot, it makes sense to quote them.
While the vehicle is stationary, pump brakes to ensure a firm pedal.
Drive the vehicle cautiously to test fit and function.
The brakes should be smooth, with no vibrations, judder, etc.
Drive the vehicle to a remote area and perform at least 30 brake applications
of 3-second duration. Use light/medium deceleration with varying starting speeds.
Leave at least ½ mile between each brake application.
The purpose of this procedure is to gradually increase the temperature
in the components without inducing thermal shock, and to mate the brake
pad and disc friction surfaces.
After the repeated stops, drive the vehicle for several miles with little or no
braking in order to adequately cool the components.
After the above process is completed, the system is ready for normal use.
When the system achieves elevated brake temperatures for the first time, a slight increase in pedal travel and pedal effort may occur. After this first 'fade' and proper cooling, the system will maintain its optimum performance at all temperatures.
