Reference is from this site: Brakes

Deore, older, and non series
SM-BH90-SS

SLX
SM-BH90-SB

XT, XTR (M8k, M9k)
SM-BH90-SBM

Zee
SM-BH90-SBS

Saint
SM-BH90-SBLS

Look at the codes after the 2nd '-' ...

Given the nature of the connections, I'd say that SS and SB stand for the connection to the brake lever and caliper respectively. I think, 'S' is 'straight,' and 'B' is 'Banjo.'

Anyone knows what 'M,' 'S,' and 'LS' means?
Why does SLX only have 'SB' in the end unlike XT, XTR, Zee and Saint.

SS = Straight & Straight
SB = Straight & Banjo
SBM, the M means that the banjo & banjo bolt are compatible with the magnesium M987 & M9000 calipers.
SBS, the S would be for standard banjo.
SBLS, the L would be for long banjo, the last S is a mystery

SM-BH90-SB = SLX 675, XT 785, XTR 985, XT 8000*
SM-BH90-SBM = XTR 987, XTR 9000, XTR 9020**

* Product info page lists the XT 8000 using the SM-BH90-SBM, a Shimano tech document lists the SM-BH90-SB
** The XTR 9020 is a aluminum caliper, you should be able to use the SM-BH90-SB with it.

I've seen a few references for a SM-BH90-SLB hose for the Saint.

"i think"

SBS - <straight lever> <banjo caliper> <short bolt>
SBLS - <straight lever> <banjo caliper> <long banjo> <short bolt>

???

the japs should fix their naming, or it might be making sense from a jap perspective, but translating it to english directly creates a scratchead.
