Shimano brake with Sram rotor?

Hi, I'm new here, just wondering if I can replace my Shimano disc rotor with a Sram rotor?

I have Shimano m395 hydraulic disc brakes which came with Shimano Deore RT56 6-Bolt Disc Rotor and want to replace it with a Sram rotor but still want to keep the brakes.

I'd really appreciate any opinions from you guys.

Cheers

As long as you get the same size and mounting type you are fine.

What about Rotor braking area vs pad area?
different calipers often have different size (height) pads
while different rotors even with the same outer diameter, can have a braking track that is different thickness(inner radius of brake track).

Tall pads, on a thin track rotor isn't great, because the bottom edge of the pad will be grabbing the rotor 'spider' legs, which can cause noise

short pads on a thick tracked rotor isn't too great either, you're wearing out only a small part of the rotor, not taking advantage of the full area

That's the primary consideration in any mix and match scenario.
I've mixed rotor and caliper brands with no issues as long as this matter is addressed.

Shimano makes brakes that use 'wide' pads and brakes that use 'narrow' pads, they also make 'wide' and 'narrow' rotors to match the pads.

https://productinfo.shimano.com/#/com...460&acid=C-461

Avid/SRAM also makes brakes that use 'wide' pads and brakes that use 'narrow' pads.
Of the Avid/SRAM rotors, the old G2 would have the widest braking area, it matches up with the 'wide' pads of the BB7/BB5 brakes, most Avid/SRAM brakes use narrower pads then what the BB7/BB5 use.

Wide pads and narrow rotors can work together but they aren't what you would call a good match for each other.

Just shim your caliper mounting position (for post mount type) with 6mm washers to perfectly align the brake pads to the rotor.

You can shim a caliper for a better fit but make sure that the pads don't overhang the outer edge of the rotor.

The Brake track on my SRAM Centerlines, measures at 15mm tall.

Go measure the Shimano Pads, if they are also 15mm tall, then in theory it can be made to work, assuming matching adaptor and rotor diameter and possible shimming to make the pads center (radius-wise) on that track.

if they are more than 15mm tall, you may have issues with the pad overhanging the brake surface -either below into the spider legs, or above off the outer edge.

I've had a few different brands without an issue, apparently I kept to the same or at least similar sizes...
