100 series brake pads in a 80 series (3 Viewers)

[v5ensx]

Thank you for the help. Here’s my situation, I drive a later 80 series cruiser and want to run the 100 series cruiser brake pads to improve longevity, which has more surface contact between rotors and pads. My understanding is all three Toyota part numbers will fit: 04465-AZ126, 04465-60220, and 04465-60230. If all three parts are for the 100 series, which one should I go with? Are all three option ceramic or is there a semi-metallic? Or is there a different part number I need to use?

Thanks in advanced.

The 100 series pads cover a little more rotor then the 80 pads. I am skeptical if there are any real benefits.

At the same time you loose the ability to quickly see how much pads material you habe left before you need to replace.

When I tried the 100 pads in mine, I found that they are thicker than the 80 ones....they barely fit without the anti squeal shims (even with rotors of unknown age/thickness compared to stock), so I tried the spray on anti-squeal stuff, but guess what....they squealed all the time. I pulled them back out and put fresh OEM Toyota 80 pads back in with the proper backing shims. No more brake noises and it stops just as well as it did with the 100 pads...or as well as an 80 stops on OEM brakes, but not any better or worse based on pad choice.

This topic has been discussed to death on this and every other LC forum.
IMO, there's no valid reason to use anything other than OEM 80 Series pads on an 80 Series with an OEM braking system.

I ran 100 series pads for a while on my old 80. I honestly did not find any difference and as @CrabCake stated, they are a very tough fit. You can certainly do it and the guarantee is you will be wiser from the experience,

If you do new oem rotors and pads and go with the 80 pads, do a proper bedding procedure to bed the rotors and that will be about as good as it gets either way.

The next big can of worms would be performance pads. There is a ton of searching to do on past threads there, but just remember, every give has a take. In the case of performance pads it is almost always shorter life span, and a LOT more brake dust.

As always, Mr T has already offered us the best balance available with the OEM pads, at least for the design of the system.

Good luck, and have fun!

Yup
100 pads are thicker, had to belt sand off 1/16 or more per pad.
Eff that.

If brake longevity is desired with the added bonus of better braking, look at Porterfield R4S pads and Brembo blank rotors. They've been in my 80 for the past 50ish thousand miles and ten years and are about half worn. I also cryotreated a pair of Brembo blanks and installed them at the same time, and they're only just barely developing a ridge. No dust, either.

Am I weird that I think that the OEM brake system in good working order works pretty well? I had some issues with mine when I got it that turned out to be the PO not cleaning and greasing the pins. I have 35" rubber, I'm running Akebono pads, and I gave them a good aggressive bedding. I've had a couple of full-panic stops and I don't really know what everyone complains about. Stopped quickly with minimal drama and I did feel the ABS working just a touch.

I guess pedal feel is pretty subjective, and admittedly I'm a bit of an ogre. The 80 does respond best to a somewhat heavy foot, but it's not a sports car. Stop driving with your ballet slippers and it stops quite well.

Just my opinion. Like I said, pedal feel is subjective.

Understandable. Not saying Mr.T 80 pads (04465-60020) are bad but would like more surface contact with possible longevity as stated. I have Toyota rotors and pads, ~5k miles or so and the pads are about half left. Yes, the 40” rubber & extra ~2k pounds heavier isn’t helping, that’s why I would like to try the 100 series pad. I can tell a huge difference between stopping power from 33 to 35 and 37. With beadlocks & 40s, it does not want to stop when the brakes are slammed to the floor. Would be a good starting point to reference between longevity, comparing the 80 and 100 series pads.

I ran the 100 pads for a while. I eventually got some annoying vibration from the front brakes. I replaced the rotors and pads (Yellowstuff) and the vibration was gone. After the work, I was looking at the used 100 pads and saw a decent lip had formed on the pad from it hanging off the outer edge of the rotor. Its possible that the vibration was the lip contacting the outer diameter surface of the rotor. If the old rotors and pads had still been on the truck, I would have ground off the lip to see if the vibration went away.
