Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
If you are using an air pressure bleeder (Motive) or vacuum bleeder (both of which are one-man operations) they don't provide any additional assistance.
Leading evidence: 'Use air pressure bleeder (motive) or vacuum bleeder (both of' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use air pressure bleeder (motive) or vacuum bleeder (both of' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
What do the speed bleeders save you over using a motive?
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hoping that someone can confirm the piston bore size on my '02 non-turbo Carrera. Factory manual has the front caliper at 36mm and 40mm pistons, and the rear calipers at 28mm and 30mm.
Previous owner painted the calipers while on the car (really???), and I intend to refinish the calipers and do a rebuild on the seals and boots while I'm at it. Also will install Speed Bleeders as I've done on all my cars. If you haven't used them, I can tell you that they are indispensable for bleeding brake systems.
Thanks in advance for any input.

Speedbleeders make the bleeding operation a true one-person affair as they have a check valve internally that does not allow air back into the system.
I am going to bead blast the calipers and take them down to the alloy. My plan is to use a high temp primer followed by Eastwood's 2K red epoxy paint, apply decals and then clear coat with 2K clear.

Speed bleeders are only needed if you are trying to do the one-man pedal pump method. If you are using an air pressure bleeder (Motive) or vacuum bleeder (both of which are one-man operations) they don't provide any additional assistance.
+996 on stainless pistons from RacingBrake. I was happy with the quaility and they�ve worked flawlessly so far.
