I have a k plate 214si that I think needs new front disc`s how easy are these to replace myself and what`s involved ?

Slide on the new discs and then reverse all the steps you've done to get to this point.

Making sure that before you fit the discs, you ensure that you have cleaned off the surface of the hub, all rust, dirt and anything else, as even the tiniest speck of dirt can give terrible brake judder as the disc is not running true. Any slight deviation on the hub, will be magnified by the time it gets out to the braking surfaces.

To give you the best chance of avoiding brake vibrations, such as judder, you want to minimise the run-out of the brake disc. This is done by selecting the best position of the disc relative to the bearing in the knuckle. If you have a DTI gauge you should put the disc on in all 4 possible positions, holding it in place with nuts rather than the screws (which are really only there to stop it falling off when the wheels are off and the pads are out and rust anyway) and choosing the lowest run-out of the 4 positions.

If you're very dedicated you should try both discs on each side of the car and pick the best overall result

Run off on discs is 3000 thou one side and 4000 thou the other , these are new so is this in tolerance ? as I have still have a problem and even changed the the drums and shoes yesterday .

Out off tolarance 0.02mm max ( 0.0008 inch old money ) take them off and make sure hub face is clean and derusted , you can put your dti in two different places ie near the hub and then at the outer edge of disc the reading should be the same .
