I need to replace the brake pads and discs on my 986 Boxster. It's got brake wear indicators which are working (and telling me to 'Service Brake Wear') and I've noticed that when you buy pads you can get them as a kit with new wear indicators.

Is it standard practice to replace the pads and sensors, or can I re-use the old sensors on the new pads? I'm not too familiar with the system used on these brakes.

they sometime break so fit new ones.

don't forget a complete damper set when buying pads also.

The sensors physically start to wear away when the pad gets to a certain 'low' depth, and therefore you can't re-use them when the light comes on on the dash, as that means they have worn to a point of completing the electrical circuit.

Obviously if you monitor your brakes closely enough you don't need wear sensors, and of course you won't need new pads for a short while. If you are going to do it yourself, whizz one of the wheels off and get a feel for how it all fits together.

I've found the 'sensors' become brittle with repeated heat cycles and generally break when you try to remove them from the old pads. Sods law also dictates they'll definitely break if you haven't got new ones to hand - a real PITA when you're trying to complete the job!

Easier just to buy new ones for the relatively small cost involved.

Also the calliper mounting bolts can 'pick up' during removal and damage the threads in the aluminium hub carrier . This is usually caused by the exposed end of the bolt corroding which slightly swells the threads . The swelling makes the bolt very tight when removing and the extra friction can damage/ rip threads in hub carrier. The threaded end of the fixing bolts poke through the hub carrier making it an easy visual check for corrosion. If the bolt ends show sign of thread swelling it can easily be dressed off prior to slackening . Hope this helps

I did this recently. The package I bought from design911 provided Pagid discs with Pagid pads - along with shims/sensors etc. Strangely the pads didnt have the holes for the sensors ends unlike Textar which I am told would do. What pads you get are luck of the draw in the packages though. I just drilled small holes to allow the sensors to slot in.

I ordered my bits from Euro Car Parts - I went for Pagid's and they were listed as supposedly having the bosses for the wear sensors. Sounds like an easy fix if they don't though smile

Yeah they have the notch in the metal plate but no hole in the actual pad material - bit weird.

But as you say - easy fix.
