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.

its the the yearly service time for me at the moment i did all four today :cool
and the brakes feel brand new again well worth keeping on top of them.

Cracking how 2. Since my mate replaced the wheel stud he snapped when changing my discs I've been having a creaking sound when applying the brake. Took me about an hour (first time taking wheel off myself) and no creaking. Thanks for the guide

Only thing I did was remove the carrier. I couldn't undo the bottom bolt and the top bolt o could t get my socket into because of another bolt in the way

glad it was some help yes that top nut can be tricky but a long ring spanner and a hammer will work
if you do not have a small socket

[richje100]

A hammer? Assuming to hit the spanner with not bash the s**t out of the bolt lol.

not if you are careful and have a long spanner but i agree this is not really recommended
the correct socket is the way forward and if you are still struggling to get to this bolt
remove the lower strut bolt this will make life alot easier

[Rusty2009]

Got round to doing this to mine today, did front and rear, seems to have resolved spring clicking noise I was getting to.

Its well worth doing it once a year also anyone doing this be very careful you don't brake the rubber sleave on the bottom slider pins they are needed to stop the caliper making noise when braking

[richje100]

Think I'll be doing this each year, surprised how easy it was.
The rubber sleeves do feel quite fragile so over time I'd expect to have to replace them

Thanks for the guide, ive been trying to explain what to do here to a local garage and theyve had my car in twice to do it as i dont have a jack to do it on my drive yet but im thinking of getting one just for this job!

Is there any need to bleed brakes after doing this or is it fairly straight forward, as in just removing bolts and greasing them back up whilst making sure the caliper is not left to dangle?
Any recommendations for a decent jack for a astra j? (i didnt get any of that stuff with my car)

Thanks in advance!
