Best method to bleed dual circuit brakes?

Post by olly22n »

Hi!

My braking system is completely dry after changing the brake lines and refurbing the calipers. It is a complicated twin servo, dual circuit system.

Does anyone know a proven method to bleed this? My mechanic has advised me to crack of all the nipples (inc on the servos) and fluid the reservoir up and let gravity to its thing until the cylinders are at least wet.

Does this sound right?

Help!

I'll be doing this exact thing in the coming weeks - my plan was to bleed the system at the boosters/servos first, then continue to the calipers.

Would be interested to hear others' experience with this.

Perhaps irrelevant for what you're doing but I bought a Bav Auto pressure bleeder ten years ago,...still the cat's pajamas.

Fill it, screw the cap on the reservoir, pump it up and bleed whatever you want all by yourself. No pedal pumping, " Down, stop, " close, up, open...
