REMOVE AND CLEAN...........

Follow the first Part of this How to and Remove the Brake Caliper and the Pads from the Brake Caliper Carrier
the only Difference is you Remove Both the 10mm Bolts and Place the Caliper out of the way
but Do not leave it Dangling by the Brake Hose tie it up so the hose is not stressed.

Now you have the Caliper and Brake Pads Removed, Pull the Slider Pins out from the Caliper Carrier
the Top Pin will come out very easily but the Bottom Pin will be stiff and will need Turning out
with a 18mm Socket and Push the Pin out at the same time with some pliers.  



Next Pull Both the Brake Pad Shims out from the Caliper Carrier
Top and Bottom and undo the Two 18mm Bolts on the Caliper Carrier and remove it.



Next give all the Parts a Real good Clean with Brake Caliper Cleaner and inspected all the Parts from Damage and Wear and Tear
Remove all the Brake Dust and old Grease from the Slider Pins, Shims And the Caliper Carrier.



RESEMBLE AND ADD NEW GREASE......

Use the Silicone Grease on the Slider Pins and coat the slider Pin with grease and Place a small amount in the Rubber Boot
do not use Copper Grease on the Slider Pins it will Corrode the Rubber
so use Silicone Grease as this will not will not Corrode the Rubber.









Next add a small amount of Silicone Grease to the Holes for the Slider Pins on the Caliper Carrier
Then fit the Caliper Carrie back on and Push the Slider Pins back into Position
The Bottom Pin will need a little Tap to get it back in.
Pull and Push the Slider Pins in and out to make sure they are Free and Moving
This will also work the Grease in Place, Then Pinch the Rubber Boots to get any Trapped air out.

The Slider Pin with the Rubber Sleeve Goes to the Bottom of the Caliper Carrier
if the Rubber Sleeve is Damaged then Replace the Slider Pins for a new Set.  











Next Take the CERATEC Grease and add a Small Amount to the Shims for the Brake Pads
This will help the Brake pads move freely in the caliper and stop them from sticking    
Then Push the Shims back into Position in the Caliper Carrier.









Next take the Brake Pads and add a Coating of CERATEC to the back of the Pads
Do not get any Grease on the front of the Pads  
Then fit the Pads back into Position in the caliper carrier.











Next clean the Brake Piston in the Caliper and add a Coating of CERATEC too and around the Piston
Then Clean up any Grease that may have got onto the Brake Disc
and then Refit the Caliper to the Caliper Carrier and Put the two 10mm Bolts back in place.
And then give the Caliper a good Rub Down to Remove any Unwanted Grease.





There is no need to Push the Pistons back on the Calipers
if you are just Servicing the Original Pads and Slider Pins
but it is Recommended you Pump the Brake Pedal a few Times after each Caliper
has been Serviced and Put back Together to seat them Correctly.      

And that is it job Done you now have Fully Serviced Brake Calipers
and this will also Stop any Brake Squeal and will keep your Brakes in Tip top Condition.
i Recommend this is Done Every Year as Part of Your Annual Service.

AS WITH ALL MECHANICAL HOW TOO,S.
you do this at your own risk if you follow the how to correctly
there should be no problems thank you.
