You need either a 7mm or 8mm Allen key for the calliper retaining bolts and that's it. Andrew ------------- Be exclusive and drive a Petrol 5 Series! Current '13 62 F10 535i MSport Auto Previous '04 04 E60 545i SE Auto '03 53 E60 545i SE Auto (Stolen) '98 S E39 523i SE Auto |

Once you have removed the pads from the calliper, open the bleed nipple/screw with an 11 mm open end spanner and you will then be able to move the piston back by hand. Just be careful that the brake fluid that now comes out of the bleed screw doesn't shoot out and land on the paintwork. Andrew ------------- Be exclusive and drive a Petrol 5 Series!

Andrew,
I thought you opened the resevoir cap to releive the pressure on the piston? ------------- Dave Ryle  "The power of accurate observation is commonly called cynicism by those who have not got it." -- George Bernard Shaw |

Id go with Andrew on this. Just my luck to mess up something in the ABS/ASC up @ the business end of the motor by forcing fluid back through the system. When undoing and tightening the bleed screw, be sure that the bleed screw is faced upward directly and also whilst winding the piston back. you can always top up the rezer when finished.(Connect a foot or so of piping to the bleed screw purely to take excess fluid away from your hands and the job @ hand.

Ok, its just I did a basic car maintenance course and he said to open the resevoir to allow the piston move. It means you only open 1 cap for doing both sides. ------------- Dave Ryle "The power of accurate observation is commonly called cynicism by those who have not got it." -- George Bernard Shaw |

Opening the cap is the traditional method but some mechanics argue that by doing this on a car with ABS can cause damage. I just opened the cap when I did mine last time and so far no problems! If you are opening the nipple then be sure to watch the reservoir for a drop in fluid - top it up with the same fluid (presumably dot 4) as the level will probably already be low and will only get lower as time goes on. ------------- Current: 2009 E60 520d "Sport" tractor Previous: 1989 E30 320i SE 1997 E39 523i 2003 E39 525i Sport Individual |

The Mechanic said that if you open the cap as you push the piston back the brake fluid will return to correct level. ------------- Dave Ryle "The power of accurate observation is commonly called cynicism by those who have not got it." -- George Bernard Shaw |

be prepared to draw off fluid from reservoir when you replace the new pads..I had to take loads out when I did fronts plus discs...is your reservoir buried under the pollen filter on the drivers side?? be careful removing the duct that fits into the bulkhead ...the plastic lugs are easily broken john |

I think that if you have to take some out, then it may have been topped up before when it had gone down. Normally, it shouldn't require this.
