BrakesDiscussions about the brake system in your vehicle and brake products.
This is a discussion thread titled "Need help replacing disc brake pads", within the Brakes forum, part of the Technical & Vehicle Assistance Forums category.
Ok, so my knowledge is a little out of date. I am trying to replace the disc pads in my 2001 tundra (without a manual) and I got my first look at a dual piston caliper. I removed the 4 bolts holding the 2 sides of the caliper together and started prying the 2 sides apart and brake fluid startin pouring out. Now I get it! there is a passage that feeds the outside pistons that came apart. I bolted them back together and bleed the line and it seems ok.
How do I replace the pads? Do I need to remove the mounting bolts or just the guide pins. Speaking of the guide pins, is there any special trick for removing these? I tapped them a few times but they did not want to move.

Thanks in advance for any help.
Whoa, Hoss! Overkill City!
You do not have to remove the caliper or the brake lines to replace pads. It's a five minute job per side, not counting jacking the truck up and removing the wheels.
All you need to do is, remove the wire clips on the forward side of the caliper, then remove the two pins holding in the pads; you may need a punch and a small hammer to tap them out from behind, or grab the heads of the pins from the outside with a pair of needlenoses and gently twist them out.
Then, take a pair of pliers (channel locks are best), grab the "handles" of a pad and the outside of the caliper, and squeeze the pad back away from the rotor. Replace the pad with the new one, then do the squeeze thing with the opposite pad, and replace it.
Reinsert the Pins, and the wire clips and you are done.
If I were you, I'd get the brakes checked by a professional just to be safe. No offense here, but if you disassembled the caliper to replace the pads, I'm not sure you really understand what you are doing, so it might be best to have it checked. Don't want you to have any bad things happen because your brakes failed.
All a man really needs for happiness in this world is a good woman, a faithful dog, and a big-a$$ed set of tires on his truck.

Yep, very easy install. Toyota definitely did us right by makin this install as painless as possible. Which is a good thing as I get 15K miles (like clockwork) out of a set of pads before they bite the dust

Cyberbilly is right you may have compromised the safety of your brakes. The two caliper hafts are sealed with a small square cut seal. If this slipped in position and was damaged or if dirt has gotten trapped between the hafts, there is a good chance you can loose your brakes. I checked in the Toyota manual and they don't recommend spiting the caliper haft even when replacing piston seals, therefore they don't give a bolt torque for the caliper bolts.
On the side of safety I will have to recommend that you now replace the calipers, but this is totally up to you. I would at lest climb under there and check that caliper for seeping between the haft at lest a few times a week until your confident that it sealed up well.
No one here want to see you have an accident because of this.
Mike
