I'm replacing my rotors (Beck Arnley blanks) and pads (Hawk HPS') however I've heard varying things. Some say not to do them at the same time and others say that doing them together is best.

I'm thinking of just putting them both on at once and performing a normal bedding procedure.

Opinions?

 

I don't see why you wouldn't want to put the rotors and pads on at the same time. If you just replace the rotors, the old pads will wear into the rotor unevenly. If you just replace the pads, they will pick up the grooves from the old rotors, which will then get transferred to your new rotors later.

 

Yeah, replace both the pads and rotors if you have the parts. You might as well flush all the old brake fluid out since it's probaby the same stuff that it came with from the factory.

 

It'll be fine. Just follow the bedding procedures included with your hawk pads.

 

Ok, will do.

I flushed it a few months ago, but I'll have to again anyways.

 

If your rotors are still smooth and don't have any major grooves in them (and meet minimum thickness spec), then I'd just go ahead and replace the pads. If they are marginal, then replace both (new rotors are not that much).

You don't need to disconnect the brake hose in order to replace the brakes and rotors so therefore you don't need to bleed the brake system again.

 

I have the whole wheel hub off (redoing bushings). I'm also replacing the calipers at the same so those came off.


Not so smooth...

 

Eh, any time you're doing brake work you should bleed the fluid, since it's a convenient time to do it and you get the junky fluid out of the calipers. I also crack the bleeders when I'm driving the pistons back into the calipers so the fluid escapes instead of being driven back up to the master cylinder. I also recommend getting speed bleeders to replace the standard ones, they have a check valve to prevent air from being sucked back in during the bleed procedure.

 

Good info. I do have speed bleeders in there.

 

Right on. Might as well tape off the calipers and paint them while you have them off!! 3-4 coats of a high temp paint will do the trick!!

 

Careful with them, my buddy snapped my speed bleeder in two by over tightening it.

 

You could break any bleeder if you overtighten it.

ALWAYS bleed your brakes, the fluid degrades from heat and picks up moisture as it ages, it's always a good time for a bleed/flush. You can NEVER have fluid that's too fresh.
