too late to bed brakes?

I'm replacing my rotors and pads soon but keeping my front pads. They've been used for about 12,xxx miles and still have about 38000 miles left on them. Could I still rebed them? Or would it be pointless?

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.

whenever replacing rotors, its best practice to pair them up with new pads as well. the face of your current front pads have conformed to match the rotors which they are currently on, and will not pair nicely with new rotors. this can cause improper bedding, partial pad contact with the rotors, and result in longer braking distances.

My front rotors don't really have any wear on them though. Should I try rebedding them or should I stand clear of that?

Why do you change the rotors if they are not worn?

Best practice is to change pads whenever you install new rotors.


If you do decide to install the old pads on the new rotors, you NEED to do the proper bedding procedure. The rotors are clear and need to have pad material deposited evenly. Actually the bed-in procedure has the purpose of covering rotors with pad material, pads don't matter much.

I got a really great deal on front and rear rotors at my local indy shop. i wish i could change my pads too i only have enough to get everything but the front pads and sensors. The only major problem is where could i bed my pads at. most of the roads down here are packed with people and sometimes cops are hiding out. The pads however, have a slight wear on it because it was replaced very recently and i haven't gotten around to hard driving for a little bit

put new rotors on, bed them in, live life happily ever after.

i go out late at night and find a straight deserted road to bed my brakes.

as long as there are no glazing issues you won't have an issue. if you want to you can hit the pad surface with some sand paper.

So I hit the pad itself or the rotor? I hear you're supposed to hit the rotors but I tried and it just made it a lot smoother. The dilled and slotted rotors I got were already sanded?
