Brake pad change, simple job....right?

Right then how hard can it be!?

Pad sensor light has come on so I guess it's time to change them. They were last changed by Porsche along with all new discs.

Anybody done this and have any tips. Anything to take into consideration further to changing standard type brake pads on a standard type car? I have the pads but what about the sensor....how does that work? do I need to get new sensors.....? My car is an S if that makes any difference......

I have a friend guiding me. he's a Senior tech at Toyota but hasn't been near a Porsche before!

Thanks in advance!
 
Well, I can say that owning both a toyota and a boxster and having changed brake pads on both, that changing them on the boxster is much easier! Yes you'll need new sensors because the one that has been triggered is no longer any use. The plastic clips where they fit into the pads often breaks too when you remove the old ones.
 
Great, thanks. Thats reassuring! The holes you speak about for the sensors....are they little round holes (look like drill holes)? I'll have to get the sensors from my local OPC then. I guess I don't need any special tools out side of those typically used in this activity?
 
You'll also need the anti-squeal self-adhesive clip things... (For the S)
If the pads have gone, the discs might well need replacing too... Unless one or the other has been changed "out of sequence" they seem to last about the same time.
The bolts are supposed to be changed each time, but many don't seem to.
 
Pad change is a very simple job, and you can reuse the anti squeel plates, just be carefull with a stanly knife - slide it between the pad and the squeel plate (they are stuck on with an adhesive) and simply slice the blade through the adhesive, once you get a start the plate comes off easilly, The adhesive left on the plate will rebond with the new pads as soon as you do a bit of breaking and generate some heat.
The sensors simply push in to the holes in the side of the pad material, they work by earthing once the plasic outer has worn through to the disk, and if your light has only just come on you will be able to reuse them as the new pad material will provide the insulation from earth.
 
There's a link to a step by step guide in the 996 forum technical section.
I've replaced mine lots of times, it's a doddle as long as everything goes according to plan :)

That's a very good point about changing the bolts. When I recently changed my discs one of the bolts snapped because they had been re-used on the previous change. The result was that the bolt had to be drilled out and a helicoil put in which made the whole job a lot longer and more expensive. The £2 a piece bolts are a good investment for the next time.

To the OP, don't worry about this story if you are only changing pads as the calipers don't need to be removed for that.
 
You need a brake wear sensor for either side http://www.porscheshop.co.uk/acatalog/porsche_boxster_987_brake_components.html, and a brake pad changing kit (the brake pad changing kit has all the clips etc for doing the job.) http://design911-px.rtrk.co.uk/fu/pt66_984_-cma81-cmo82/Porsche/Boxster/Pin-Kit-and-Guide-Plates/ You'll also need a tube of copper grease, and a brake pad spreader will make the job easier. Don't forget something for taking brake fluid out of the reservoir (a pipette or similar).

I did mine a few months ago (took a couple of hours)- you will need new sensors- they are impossible to remove from the pads- even when the sensor hasn't activated yet.
 
Copper grease is a no...no for brakes , you should be using the stuff from pagid available at german swedish and french or VW dealers. Its about 4 pounds a tube. Ask the parts counter for brake pad assembly paste.
 
Last Months 911 & Porsche Magazine had a step by step guide to changing Boxster pads and discs inc. photos

good article

Always used Copper Slip on the back of pads, never had a problem, its recommended in many motoring puplications. I don't think its a grease! When I worked for a Mercedes garage it was standard practice.
