brake rotor and pad replacement question

[994runna]

I just put new brake rotors and pads on my 99 4runner, and during regular brake application, the brakes seem fine, but under hard application, it takes a little longer to stop than it should, i bled the brakes after i finished the install, and there was no air in the lines, any suggestions on what the problem could be? maybe i reversed the pads, or something, I dont know

Help me out

Why did you bleed your brakes? Anyways, did you start with the wheel farthest from the reservoir? I would bleed brakes again in this order: rear passenger/rear driver/front passenger/front driver. And do the bleeding process ( open bleeder for few seconds) on each tire until no air comes out. This has always worked best for me when I had to bleed my brakes.

If your pads are on backwards, then I guess you should check.

After putting new pads and rotors on several vehicles I own, including a motorcycle, quad, wrx and a few others I can say I've noticed when putting on brand spanking new pads and rotors they do take a while to seat and perform correctly. Also did you spray brake cleaner on the rotors before installing them? They usually come shipped with a protective coating to prevent rust, so it's a good idea to clean them up.

But if you messed up bleeding the brakes you could have a completely different problem.

1. Bleed the brake in this order Front Driver-side, Front Passager-side, Right(Rear)-side, Left(Rear)-side.
2. Do the brake in if you replace rotors.

Why do you suggest bleeding that way. From my experience and knowledge, you are suppose to start with the tire furthest from reservior and work your way towards it. That way air gets purged through longest route first.

Everyone has their own way of doing it. There is no right or wrong way.

Well this is the total opposite of how I have always done it and the last time I did it on my 4runner, my brakes work better than ever. So I guess to each their own. If it works, it works. Good luck 994runna! :shrug:
