replace all four brakes pads and rotors

For how long? 100k+ intervals on brakes with these cars. My guess is they'll be well below spec before the 2nd interval is done. Maybe not in the desert and where people go 60-70k a year and barely touch them. In New England they're gonna be trashed. Not the greatest pic, but those are 2 1/2 years old. I doubt most people are doing the math to see how much wear came off the rotors to see if they're more then half worn. Above minimum? Send it.......

I'd rather just change them once and have them go the distance then change them out halfway. The less downtime the better.

 

Yeah, when they've got chunks out, that's not really spec.

 

I get what you're saying, but those are less then 3 years old. I have a hard time believing people still have rotors in spec to make 2 pad change intervals in the majority of the country.

 

Boston Mass is salt central?

 

They love liquid salt here. It's killing things fast. I had to drill out a caliper pin last year

Absolutely in the rust belt.

 

Around here our local small mall is terrible, maybe managed by a litigious lawyer: there was still plenty of salt in blazing-sun spring.

 

I find it helpful to clean and lube the threads in the rotor "hat" before trying to use the bolt. If the rotor doesn't want to move with about 20 ft/lbs of torque on the removal bolt, then use a large hammer to hit the edge of the disc. Spin the rotor 180* and hit it again. Put a little more torque on the bolt and repeat. Then scrape all the rust off the hub and put antiseize on before fittong the new rotor.

Before you rotate the caliper pistons back, gently pull the piston boot slightly away from the piston - you don't want it to stick in its groove. I use a small bit of silicone spray to help it along once I've unstuck it.

You're fine. The purpose of those shims is to help prevent vibration noises. Some pads come with them, some don't. Depends on the design.

Congrats on your first brake job!

 

Should I change the rotors?? My 08 has 160,000 miles. The rotors looked fine actually although I did not measure them, BUT I just put on new pads yesterday and got to thinking maybe new rotors a good idea now and then can forget about the front brakes for another 150,000 miles by which time I will be 104 years old with my current usage rate.

 

As long as there is not a lip on the outer edge, and there is no pulsing while braking,
you should be fine.
