100 series brake pads

[BreckenridgeCruiser]

First off, I did search, but didn't find what I was looking for.

I need to put new pads on the front of my 94 FZJ80. I have heard that a lot of you have put 100 series pads on as an upgrade.

Could somebody tell me what the steps are to do this? Is it just swapping them in or will some work need to be done? what is the advantage to doing this in the first place?

Thanks!

I am subscribing and answering what I can because I was in the same boat a few months ago.

The advantage is they have more contact area and supposedly last longer. Members argue over wether or not they "stop" any better.

I would like some step by step instructions (with photos) because I didnt see how larger pads would fit.

Any specific years?

I have the 100 series pads in my 97. Its as simple as changing your pads. Your shims will not work, so you have to install them with out them.

The main difference is the 100 pads, which are larger that your stock pad, will have more surface area hitting your rotor... + better stopping and longer pad life.

Are these only for the fronts? Is for the rears as well?

I put 100 series pads and oem calipers on the front of my 94' without whims because that is what I have read on the forum.

My question is: has anyone ever had the pads rattle around in the caliper? After doing the above I developed a rattle that goes away when pressure is applied to the brake peddle. Check everything out and the only thing loose was pads.

I put a set of these 100 series pads (o'reilly part #100.07720) on my '95 about a month ago & am very happy with them. No, they're not Toyota pads, but they were in stock when I went to my local store. I would say that these pads might offer just a little extra bite over the ones that were on the truck since before I got it in December of 2011.

I know these pictures aren't great (cell phone), but you can see the difference between the used 80 series pads on the left & the new 100 series ones on the right:

& the 100 series pads stuffed into the 80's caliper:

I've had no issues with the 100 series pads I've been using so far, but I have used CRC Disc Brake Quiet with good results in the past. Basically you paint it on either the back of the pad, or the edge of the piston & install the pads as normal.

After looking at the design of the pistons & seals on the 80 series calipers I would recommend applying it directly to the edges of the pistons in the calipers rather than coating the entire back of the pads. This should allow the pistons to "adhere" to the pad backing without the seals sticking to it as well. Once the bond is made the pads should retract from the rotors along with the pistons when the brake pedal is released. Since the pads are no longer just "floating" in the calipers, your rattling should stop.

I would also recommend using a brake lube on the pins & the portion of the caliper where the edges of the pads ride for smoother operation.

If you use the brake quite & lube sparingly you shouldn't run into any issues with excessive dust/dirt/muck build-up, even when wheeling regularly.

Ive put 100 series pads on my 92 (smaller calipers than the 93+)

I did have to remove a bit of material from the pads on the bottom corner, not a portion of it that presses against the side of the caliper, it just protrudes further towards the hub then the stock pads.

It does stop better, but my old ones were garbage...

Search is your friend - lots of discussion about 100 series pads on an 80. Front ONLY!

Consensus is that you should swap out your rotors at the same time as the wear pattern is much different. 100 series pad is thicker and has a larger surface area as has been mentioned. They will not fit with the shims, so you have to ditch those. I did mine years ago with a birf job so I changed out the worn rotors and upgraded to the 100 series pad at that time. They do last much longer than the 80 series pad. I usually got around 15K on an 80 series pad and I changed out my first set of 100 series pads at 20K just because I was headed out on a long road trip. They still had some life to them.

What if i have a friend at a machine shop who will sandblast any rust off of my rotors and then turn them on a lathe?

Waste of effort. By the time you remove them you might as well put new ones on that are thicker. Brembo discs are less than $100/pr. How much is your machinist friends time worth?

He was gonna do it for free. Doesn't get paid by the hour.

i need to have this planned out when i need new pads. when i go to the dealer, what part number should i give them for the 100 series pads? or what year of the 100? i remeber there was a specific year because they are not all the same

 

[Hoosier Daddy]

The OEM part number is different after 2003, IIRC, but either works fine. I put the newer version on my truck recently and they were oversized in both area and thickness just like a previous older set of the 100 series I had.

FWIW, some auto parts stores only list one part number for all years of the 100 series, so there can't be too much of a difference.

 

[86tuning]

Probably an updated pad compound. Toyota tends to change pad compounds every now and then. Usually to combat noise complaints, but since we aren't running 100 series rotors and calipers, I wouldn't worry one bit.

Interesting ..... was always wondering if it was doable with the smaller calipers.

Got 16 inch rotors already but did not want to buy new calipers.

Or you could just call CDan and tell him what you want to do. Easy. Very likely a better price, even after shipping, compared to your local dealer.
