Lazy Piston Definition: When one pad wont come as far back as the other, and usually rubs on the rim.

Tools required:

• A track pump - example
• 5mm allen key
• 3mm allen key
• 8mm Spanner
• 5mm/4mm allen key - Depending on mount bolts
• Bleed kit - especially the hosing and hose connector!
• Oil
• Mole grips/pliers.
• WD40/GT85

Method:

1. Take the Magura off the bike. I'm sure you know how, take off bar-end, grip, slide off lever. Undo mounts, and cut off any cable ties or anything holding the hosing on your frame.

2. Take it apart. Please note: Be sure you're confident with bleeding it once you're done!

Undo the bleed bolts, and then the hosing.

Make sure you don't make a mess with all the oil/water going everywhere!

3. Now all that's off, you'll have the two pistons/slave cylinders on their own.

4. Take one, and attach the bleed kit hose to it. And the other end of that hose, you attach to your pump. - As you would a shraeder (car type) valve.

And pump the pump. This should blast out any crap in the piston. It's handy to get the mole grips and clamp the nipple, then turn it so it's against the prongs of the slave cylinder. - This will pull the piston out a bit.

Also spray some WD40 all over it, in the hose holes, and on the piston. Even fill up the clear bleed kit hose with WD40, and pump it through. Do this like a mad man untill you're happy with it. Then do the same to the other one.

5. Now that's the slave cylinders sorted. Might aswell clean out the lever. Take it all apart. - Undo the lever bolt, and out it all comes.

You can kinda see it, but there is a lot of oil and general crap around the bolt hole. Just rinse it with water, and scrub it all off.

6. Don't be thinking that's it with the lever! Remember what you just did to the slave cylinders? Do the same to this. Fill it up with oil through the bleed bolt hole, and pump it a bit. This will lube it all up. Then attach the hose and pump to it, and pump away! Once you're happy with that, put it back together.

7. Now you've got all that clean, you need to bleed it and refit to the bike.
