Wheel noise: Time for brake job?

[CA_Boxster]

Hi. I have a 2000 Boxster with what I thnk are the original brakes (I bought it used). It has 48k miles and the last 28k are mine. I know my brakes were down to 6mm front and 8mm rear about 8 months ago so it's about that time, but I have a question. Tonight I started to hear a squeak when backing up and it seemed like it was on just 1 spot on the wheel (I don't know if it's front or back). I rode around a bit and braked hard a few times to see if it was just dust but that made it worse. I'm pretty sure there's a bit of rubbing going on. When the brakes finally go, is it normal for it to seem like they're almost too tight? Meaning, would I be hearing and feeling contact on the rotors now? Like I said, it's about time to change the pads and rotors anyway, but I want to make sure that's all I'm hearing.

The sensor never indicated that they need to be changed, but I don't know if I trust the sensor anyway.

Thanks.

Trust the sensors.

Unlike some manufacturers, Porsche fits a sensor to each and every pad. If the brake wear indicator is not illuminated, they are unlikely to be completely worn out. By al means do a visual inspection, but it's highly unlikely your squeak is being caused by the pad backing plate contacting the rotor.

Good Luck

You're right. It's in the shop today for other things and in looking over the car they said there is still room left. I probably have another 6 months to go on the fronts. Thanks for the reply.

On the other hand they came up with a cam cover oil leak so I'm getting a bill today regardless...

This was well covered in New Zimmerman/Mintex Squeak topic I think!
