When a leak occurs in one service circuit of a multi-circuit braking system, the leak can prevent replenishing the non-leaking service reservoir. To address this problem, a shared backup reservoir can be used to replenish the non-leaking service reservoir. A valve can be used to allow flow from the backup reservoir to whichever service reservoir is under higher pressure, as low pressure would indicate a leak. Additional valve(s) can be used to impede flow from the service reservoirs to the backup reservoir to prevent the service reservoirs from being drained if the backup reservoir is subject to a leak.
