Time for Brakes

[xclusivecar]

I'm not necessarily talking about the $12 to $20 sensors. Most people get their brakes done when something is already wrong...like grinding sounds or brake shudder. Now your looking at rotors, pads, labor, it adds up quickly since I believe you cannot turn the rotors on a Porsche. (Not sure but this is what I have heard).
What I am saying is if you wait for the brake light to go on and the previous owner had this sensor removed you will be waiting for a large repair bill since this light will never go on to warn you. Get the pad thickness measured to be sure of an approximate time before they are due for a change. You can measure them yourself very easily if so inclined. This gives piece of mind instead of just "waiting for the light" and you can change your own pads VERY easily!
In short...the light should ONLY be there to be a final warning to you to change your pads. YOU should be aware of your cars needs before the car finally tells you something is wrong.


BTW-After you have changed the first set of pads you will be amazed how easy it is to do on this car! It will take longer to take the wheel off than the change the pads!

Porsche is the easiest brake pad job known to man. The info you got on renntech should be enough. Do replace all of the sensors since, as you stated, they're only about $12 each and the plastic clips on the ond ones will fall to pieces when you pop them out.

If you use the Mintext pads for low dust mentioned above, make sure you get "Mintex Red Box". The Mintex pads don't have the hole in the top for the sensor, but you can drill it yourself very easily. Just slip bits into the old pad until you get the one that fits, then mark the depth on the bit and drill it into the new pad.

Something else you may want to use is either the brake pad dampers or some spray Disc Brake Quiet to put on the backs of the pads. The spray is cheaper, but you need to make sure you read the instructions and do that right so won't squeal.

One other thing that's good to do is measure the thickness of your rotors while you have the wheels off. You can pick up a good measuring guage at an auto shop or hardware store to do it. Since the rotors wear a lip on the outside, you need to take two quarters or something else that's small and flat and measure the thickness of those. Next you put the pieces on either side of the rotor so they are sticking out past the lip and measure. Subtract the first measurement from the second and you have the rotor thickness. The minimum thickness is stamped on the edge of the rotor. If you're right on the minimum, you may want to replace them since they'll probably warp or crack when they get too thin.

Good luck!

Rotors can be turned, but most shops won't do it because there's only 2mm between new and minimum thickness. They are afraid they will take too much off and you will expect them to replace them all.
