When replacing the brake pads, is it mandatory to replace the shims and sensors, too?

 

It will be highly unlikely that you are able to save the sensors. We replace the shims also.

 

Because track use I go through a lot of pads. In the past six years I have replaced one sensor. The rest of the sensors and and shims are original.

 

I have never replaced a sensor. But I have changed my pads before the warning comes on.

 

Thanks, that's what I thought. I brought the car in to have the pads replaced with new oem ones, I've been presented a bill with six line items. I'm too embarassed to say how much.

 

It is standard operating procedure for a licensed shop to do new sensors and shims with new pads. Most DIYers will reuse sensors and shims.

Don't feel too bad. Because I use expensive track pads I probably paid four times your pad replacement bill in just pads last year. It is a crazy hobby.

 

note aftermarket sensors are about $3 each. I just tie mine off and zip tie behind disks when I put the track pads in in spring. why replace the shims?
Brooklyn which pads did you go with?

 

Because if you leave the old ones in too long, they rust into the piston and are extremely difficult to remove.

 

shops of any type will not turn rotors any longer either due to liability reasons even if they remain with in spec. that's why the "$39.99 an axle" coupons you see from time to time always make me chuckle.


I have not done the pads on my 6t yet, but when placing pads on my old SC racecar it always steamed me the pads were more expensive than rotors and lasted half as long.... im yet to get familiar with the new car's pad & rotors will set ya back....

 

Just stock oem pads.

 

Are the rear shims on the standard Turbo 30mm, or 28mm?

 

I was in a shop a couple weeks ago that had a machine that was turning a rotor while still on the car! Albeit wasn't a high end shop I'd never seen or heard of a machine like that. The tech told me it takes just as long or longer to set it up as it does just to pull the rotor.

 

Our Chevy shop turns rotors all the time. They did the ones om my 4S with no issues whatsoever.

 

Never turn rotors basically the pad is done then the rotor is done. Always a new pad sensor and most of the time shims unless using certain brake pads.

 

I thought turning drilled rotors is a no no!
