    I don't know how else to word it. Installed new front pads (Toyota pads) this weekend, but today is the first day that I've driven it more than around the block. I noticed a pretty strong "hot or burning" odor when I got home. New pads probably have less than 25 miles on them. Is this normal? If so, how long does it last normally? Just want to make sure nothing is amiss.

    it could be normal some pads come with a plasticky coating on them to protect them, its probably that just burning off

    make sure that your brake piston was pushed all the way in.

    If it is still in the old position, it will cause the new (thicker) pads to have constant friction against the rotor...and burn em up.

    I don't understand how that could be. I pushed all the pistons in in order to be able to install the pads. Do they not just then extend to push against the pads when in use and retract when not being used?

    They retract to a point. Sounds like you installed them propperly. How hot do they get? Are you just smelling somthing?

    take a quick look at both rotors for any signs of discoloration of the rotor (blue or purple) If you really dont see anything like that more than likely the pads are just bedding in. to help with this bring the truck up to 60mph brake with firm preasure down to 20mph do this 3 to 4 times. Than let things cool a bit and do 60mph to 0mph 3 to 4 times you might smell hot brakes at this point. let things cool again and you should be good togo

    No discoloration. And they don't appear to be getting any hotter than usual. Just the smell. I've actually been riding around with everything off to make sure I could hear any rubbing or anything out of the ordinary. They are as silent as my originals. I've actually VERY pleased with that part. Thanks for the input. I'll give them a few more days and make sure the smell goes away once they have been bed in good.

    I recently had the pads on my front brakes changed at a garage and I've been noticing the same burning smell as OP has mentioned. I have also noticed that my stopping distance seems like it has increased greatly as well. Do you guys think the increased stopping distance is caused by some excess oil or something left behind or is it something else?

    Honestly, it doesn't say on the receipt and the mechanic never mentioned it to me. I also got new front rotors so do you think it might be some grease from that? Also, I just got back from a drive a few minutes ago where I did some pretty hard braking and I noticed the burning brakes smell and some smoke coming from the front brakes. I didn't notice any pulling so I don't think it's a stuck caliper.

    Smoke, constant burning smell, new rotors,new pads, rotor spins freely, no seized piston in caliper. I dunno, but I think you need to get with your mech. & go over what he did/didn't do, sounding more like an install issue at this point...

    Actually, I drove it a little bit more and everything is fine now. Must have been some extra grease or something because the burning smell/smoking is gone and the stopping distance is back to normal. Thanks for the help anyway, guys.
