bald tires wearing out brake pads?

I got my brake pad/sensor warning light come on for the 3rd time in under a year, and I suspect that my worn out front tires are causing me to brake harder than normal just so I can stop normally. does anyone know if worn tires play a role in the life of your brake pads?

If you're braking harder than normal then yes, your brake pads will take more abuse. You also should know that having larger diameter rims without taking into account an upgraded brake system means you'll be putting more strain on your stock brakes. Why? Plus-sizing also means you're creating more rolling mass that you inevitably have to slow down. This can cause your brakes to wear much faster.

It's easy to check if your pads are really bad or if it's a faulty sensor. If you're lazy you can check just your outer pads, but if you want the whole picture, take off each wheel and check both the inner and outer pads for wear

Lastly, having bald tires is inexcusable man. Tires with adequate tread are just as important as having a properly maintained brake system. There's competitively priced tires for practically every size. Drive safe!

it's the tires that stops the car.. not the brake discs... so.. if you think in that logic.. yes, it plays a big role.

I don't think this makes sense. If your tires are worn out, then you have less grip available to brake. That would imply that you could only use, for example, 70% of your available braking power before you got into the ABS. At that point, you wouldn't be able to brake harder than normal to stop any faster.

Worn out tires will not cause accelerated brake wear. Worn out tires will also not cause you to brake harder.

it's a steptronic car. just got the brakes serviced today and they replaced both front pads.

apparently they will either check front or rear rotors, front or rear pads, and replace only what needs replacing on both sides IE front L/R pads or rear L/R rotors.

Quick question related to this.... was getting an inspection on my car and the mechanic tells me that my front brake pads and front rotors are worn....

Now I thought that I would get the warning light come on the dash if this was the case, but it hasnt? How does the warning system work?

Warning light is for pad thickness, not rotor thickness.

The indicator is for when the pads are really thin. I'm not surprised that someone told you that they are worn before the light came on.

Yes when the light comes on the pads are literally gone they have NOTHING left in them so that is true

Not unless it's destroyed. Turn the key to the on position, but don't start. Leave it there for 30 seconds (maybe 60? Don't remember...) and it should go off.

Yes, once its been tripped the sensor is ruined.

Oh right... For some reason I was thinking that you had disconnected it and the light was on. Yeah, if it lit because your pads are worn, it's toast.
