What Pads fit the Shimano XT M8120 brakes?

[JC1982]

Hi all

I am asking this question as when I Google search for these pads. I am getting pads come up and when looking at the spec it's not showing Br-M8120 or M8120 it's compatibility with ZEE, Saint, M8100, M8020 and so on.

I understand shimano try to keep pads in the same ranges as much as possible.

Any pointera would be great.

Thanks.

These look like they fit the M8120 and lots of others so you should be able to find some in your preferred brand or compound;

That's great thank you. They didn't come up when I was looking.

Thanks again

Just ordered two semis for the front and two sintered for the back.

How are you finding the E matrix ones and how are you finding them compared to normal pads?

Thanks

I haven't tried the normal uberbike pads, but e-matrix pads feel a little stronger than the stock finned shimano pads that came with my brakes and a little quieter too

I've just had some galfer pads delivered, but not had time to fit yet. Only chose them as they were the only ones I could find in stock, so no idea if they're any good.

If you would mind let us know how they go lads. I am still 100% on specific parts yet. However if they do work better the its worth paying the difference.

Thanks for mentioning these, most Shimano are out of stock at time of writing this, searched their e-bike pads and found M8120 in the description for one, and I've received these replacement pads next day. Haven't fitted them yet but will report if they are noticeably different in feel to the stock N03A's.

Update - I went to fit them and cracked one of the ceramic brake piston when pushing them back with a large allen key. Lesson learned, and the new brake calliper came with original shimano pads in, so I haven't tried the after market ones yet. Expensive lesson in brake maintenance!

Just done exactly the same and after having spent days cleaning disc rotors, scuffing them up with emery paper, cleaning the pads with alcohol only to find eventually that there's brake fluid pissing out of one of the pistons. Looked on line for a seal and piston kit but only from China as Shitmano, of course, doesn't make one, and after watching some youtube vids seems that they are not the best fit. So have to buy a whole new caliper... what a waste.
Does anyone have a fool proof method of pushing the pistons back in without breaking them. I've must have changed pads about a dozen times over the years and usually use the old pads with a very large flat blade screwdriver in between them, twisting and levering them to push the pistons back in, always worked before but not this time so open for suggestions and ideas please.

Park Tool PP-1.2 does it for me. Can get them on Ali as well​

@Husky430 Did you undo the screw on the brake lever to allow the brake fluid to move. I also screw in a syringe into the fitting so that I neither make a mess nor waste any fluid. To be absolutely certain not to suck any air in, add a bit of fluid to the syringe. As long as the pistons are not actually stuck, they will move.

Yeah Steve I did undo the screw you mention and used the gravity method where you completely remove the bleed screw on the caliper to flush the new fluid through from the brake lever reservoir using a Shimano "bucket" that screws in to the brake lever and allows the fluid to flow down to the caliper. I'm thinking now that I just must have applied uneven pressure to one of the pistons and cracked it.
New calliper on the way and will use a wide bladed chisel in-between the pads next time to try and get an more even job on them.

Put a plastic shim in between the piston and your screwdriver.

That's sort of what i was doing with using the old pads between the screwdriver and the pistons, still managed to break one... clumsy or over enthusiastic

I like and use these. Work as well as Shimano finned.

Don't try the disco inferno on these!
The XT and below are steel backing plates.
Hmm just thought, not sure about the fins on the XT finned pads.

I run those pads on the front. I get them from Aliexpress. But have been using $7 for four pairs, Aliexpress 4 pot pads, on the rear. They only last half as long, <about 500km> But they work really well. The rotor doesn't seem mind them either.
