Bleeding Brakes

atomsplitter said:

There is an option to use TuneECU to activate the ABS solenoid and a great big warning before you use it. Ideally the ABS fluid would be changed out when you do a flush and refill, however that requires activating the system electrically to open the valve. The Rocket however is an open system so there isn't a need to activate the ABS, the shop manual provides instructions for simple brake bleeding when renewing the brake fluid.

abs bleed never works with Tune Ecu OR DEALER TOOL . CO . UK , BOTH companies/developer said to me in writing that it will never work and wont be supported.

I’m thinking then a regular brake flush will be just fine.

I've had a professional vacuum brake bleeder that hooks up to my compressor to bleed brakes on all of my bikes for years. Can I do the same with the Rocket3 and vacuum out the old fluid at the calipers?

manual bleed trumps every other method IMO.

I did the reverse brake bleed starting left front caliper. It was challenging with the angle of the bleed nipple pointed inward. And messy, having brake fluid squirt out at times. Lever was still good when done. I tried it again on the right side and wasn't pleased with the progress so went with my Mity Vac pro bleeder with good exchange. I found the lever went soft so I opened the master cylinder bleed screw and fixed the lever to like new pressure. The rear bleed procedure was easy and exchanged fluid several times. The result : very good brake feel front and rear, surprised at how much improvement actually. BTW tested fluid before bleed and showed high moisture content . Definitely a regular two year maintenance item.
