Tundra brake upgrade Pads WTF?

[Capnemo]

I am looking at RockAuto rotors, calipers, pads, likely going Raybestos coated remans that come with hardware and pads with pads (RC11549C $80+core each), and Raybestos Element (96931FZN $27 each) or Brembo (09819681 $49 each) rotors.

But looking at the different pads I would say over half of them are chamfered at the leading and trailing edge, this sacrifices maybe 15% or more of the potential
braking surface area of the pads. Looking at FleaBay some Toyota boxed pads (real or fake) are chamfered and some are not.

Is this an anti squeak thing? I would rather have all the pad contact I can get.
And why at the trailing edge, do we care going in reverse, or is this to make them Right and Left compatible either side I guess.

Just puzzled why some pads are continuously flat and others are steeply tapered at the front and rear edges.

Short answer to your question is the chamber of the pads is to reduce the likelihood of it causing extra noise of catching on the rotor during braking. It’s up for debate if it helps or not. Personally, I’ve never had a problem with flat pads or had any customer comebacks for them.

My Dad has worked with Federal Mogul and Wagner Brakes for over 35 years. Short answer to your question, the pros of the chamfered pads greatly outweighs the cons. The loss of surface area is mitigated by the ability for the pads to dissipate heat and reduce noise. I’m buying Wagner pads next break change.

Where are you looking at buying your rotors? Off a scrap Tundra?

Cool story bro

You must be the life of the party. I took the time out of my day to help someone and you contribute this way.

There's always someone who feels the need to chime in with a completely worthless comment.

One thing you'll notice between chamfered pads, and flat pads is what they're made out of. Depending on what the pad is made from is a big determining factor in how to the pad is cut/chamfered.

As others have said, chamfers can control how the edge of the pad interacts with the rotors and can help prevent noise. They do this by making sure the largest possible edge of the pad makes contact with the rotor. They can also help to compensate for flex in the pad on some applications that use a long pad.
