Ford Focus MK1 front brake caliper repair, seized caliper, seized brake cylinder repair

Hi all

Ford Focus 2004. Mrs noticed a grinding noise and noticed some friction while car was rolling slowly and then it stops like you gently use your brake.
It appears to be front LHS caliper.
As caliper was not to bad I ordered caliper repair kit, the simplest and the cheapest - just some grease and rubbers.
Below step by step how to fix it and save some money
 Repair kit (around 10 pounds)

 There are 2 bolts holding the caliper. Allen key is needed and it is not standard size so make sure you have  the proper size before you start your fixing ;)

 Remove plastic cap protecting bolt









 Remove anti-rattle spring



 Take of the caliper from disc

As you can see piston is corroded and below all rubber collar is in  very bad condition



 You will need to push out the piston. Simply pump the the brake pedal until it leaves the cylinder. KEEP AN EYE ON BRAKE FLUID LEVEL AND TOP UP IF NEEDED AS YOU MAY GIVE YOURSELF AN EXTRA BLEEDING WORK.

 Cylinder inside looks not that bad. Does not need to be replaced



 Using sandpaper  (I used 1000 grit) you will make both piston and caliper shiny new. Make sure you properly clean piston and caliper as you don't want any metal or stones left inside the caliper. This is very important



 Use the new rubber collar and provided assembly grease. This will help you to push the piston into the cylinder







 Make sure cylinder is very tight and slightly push it back. I used the caliper tool






 Check if the collar is on it position



Check the brake fluid level and top it up if necessary 



There is another sachet in kit. Use it too 





Caliper bolts torque: 28Nm
;) Allen key: 7mm

Last thing: bleed the brake system.

Thanks!
