Bleeding method decides how the fluid is moved through the system and how many people it takes. A vacuum bleeder draws from the nipple end. A pressure bleeder pushes from the reservoir. Both let one person work alone, which is the practical reason either is bought over a length of tube and a helper.
Power source then decides how sustained the work can be. A hand pump needs pumping to hold pressure. A pneumatic unit runs off the air line and holds it steady. A 12V automatic unit at 6 bar and a 240V electric unit at 0 to 4 bar hold a set pressure indefinitely, and the 240V machine is stated as ABS compatible. Sykes hold 12V and 240V automatic machines with the Brake Pro portable range above them.
Reservoir capacity sets how long the work runs before refilling, from 500ml on a hand unit up to 20L and 60L on the trolley-mounted Brake Pro machines. A 1L or 2L body suits a single vehicle; the large machines suit a bay doing this all day. Sealey run vacuum, workshop and pneumatic bodies at 1L, 2L and 3L across the middle of that span.
Cap fitment is the part most often overlooked and the part that stops the job. A pressure bleeder needs a cap that seals the reservoir, and reservoirs differ by manufacturer, so the cap is matched to the vehicle rather than the bleeder. Bleed screws and nipples are held alongside. Send the reservoir and the vehicle over WhatsApp on 07754288583 and the cap fitment gets matched from there.
