Sram rival brake failure

[Eziemnaik]

(Yes, I have just found out touching this liquid is not recommended)
I have just had a complete failure of rear brake, upon inspection liquid came out through this tiny pinhole next to serial number.
Pistons are not moving at all, it seems no pressure at all in the system
Is the brake salvable?

I suspect it's probably all fine, might just be that the bladder under the cover has ruptured. You can buy a replacement cover and bladder if needed:

Then you would need to refill the system with fluid and bleed it.

SRAM recommends you clean off the spilled fluid with isopropyl alcohol, the brake fluids not great stuff and can cause damage to your paintwork, rubber covers etc.

If the bike was left in a very hot place then the fluid may have expanded sufficiently to ooze out through that pin-hole
