Is it okay to replace both the front and rear brake pads at the same time?

It says that there there is a break in period.

 

yes you can replace them at the same time, break in period is to bed them in, so take it easy for a while leaving yourself a bit more time to stop

 

You can accelerate the bed in period somewhat. Finding an empty parking lot and running the brakes through a succession of heat up and cool down cycles. But, like wheel nut says, take it easy for a few miles and you'll be fine. Fwiw, I always replace all my pads at the same time, even though I don't use my rear brake much.

 

I will be replacing all my pads, lines and fluid next week. They say to go easy the first 40-50 miles after that for break-in.

Don't forget to clean the rotors of any old material when you replace them. I'l be using a Scotch-Brite pad and some soapy water to scrub them.

 

Okay cool!!

Am I supposed to clean the inside of the calipers too? I didn't do that when I replaced my rear brake pads the other day.

I guess I'm going to go get some brake cleaner to clean the rotors/inside calipers.

Just curious, what would happen if I didn't clean the inside of the calipers/rotors?

 

Soapy water w/ and old toothbrush works the best on the pistons! You can use brake cleaner, but soapy water works the best. And an old toothbrush works like a charm - like it was made for it.

You don't need to clean it so long as your pistons are moving evenly. However, I doubt they are, and it could use a good cleaning. If your pistons don't move together, it causes un-even wearing on the pads
