good morning,
can anyone tell me that when i buy new pads for the front of my e53 they come with a new sensor lead or do i have to buy that seperate,also is there any how to articles on doing job? i found one for rears but not fronts,many thanks in advance

You have to buy the sensor separately...

Wheel off
Allen key (7mm I think) at the back of the calipers - top and bottom
Prise piston back
Add copper grease to back of pads to stop the brakes squeaking
Remove old pads
Replace with new pads
Bed the brakes in

Vague description but not much to them (similar to rears). Pewters kindly did mine and may be able to expand on this. Just be safe when doing the job.

Sensor is about a tenner.

I'm led to be leave that if you buy OME then they come with new sensors, I don't have a guide as Ive never needed one for doing brakes.

Ok i may be wrong in the sensor part

Just to add to sanj's you will need the remove or un screw your brake res top up, because if your fluid is high and your pads was low, fitting new pads may result in naffing your valve up.

I replaced mine with Axxis pads, took me 15 minutes per corner including cleaning the wheels on the inside

Sanj described what needs to be done, just be careful when pushing the pistons back that you don't overflow the brake reservoir.

is the sensor only from dealer? many many thanks for all your help as always

No, you can get them from ebay much cheaper (between £6 and £10).

Before you push back the piston, take off the resevoir cap and wrap a rag around the neck of the resevoir. Any spillage will be soaked up.

Put copper grease on the back of the pads and not the front. You may laugh but there are some real numpties around.

The fluid should be ok if it has never been topped up, as the lowering of the level is caused by the wearing of the pads.

Yeah, but it adds a whole lot of fun to the process.....

..and just for the odd numpty: Seriously, do not try it!!
