I use a hand pump vacuum bleeder , holds about 4l of fluid . Pulls out @ bleeders . Can also attach to shop air . I prefer not to use shop air as quieter .
If i want to reverse bleed i use a 600ml coke bottle , hose out of lid to caliper , hole for air blower in and use zip tie to only have low pressure in .
Hand vacuum pump is plenty strong to also pull diff gearbox engine or trans oil
