Master Cylinder repair kit, still no front brake

Thanks man appreciate the advice. Somebody else told me to check the pistons and seals in the caliper too. They can let air in the line as well.

No problem, glad to help. Thats possible but I still think you'd see leakage if seals were going. Your original problem points to a master rebuild which you did. I think now its just a matter of getting brake. Air can be trapped in a lot of places... BTW I am not a wrench, I do a lot of mechanical work but am not a professional. Just so ya know.

I'm attempting to learn. I called my harley dealer for help and even to let them fix it but they won't touch anything to do with the brake system. I will try pulling more air out and see what happens

I bled mine a couple months ago, and they were a bit stubborn (went through two bottles of fluid). U started with a vacuum pump, then switched to the old fashion way of a wrench and empty collection bottle. After I got just about all the air out, I squeezed the lever and zip tied it down all night. The Next day I bled a couple times and was good to go. Sounds like you have trapped air or a stuck piston. Squirt come brake cleaner on your pistons too. Good luck

If pulling the brake fluid from the master cylinder down to the caliper rather than pumping the brake lever to push the fluid down you'll want to secure the lever at about half pull to open the port inside the master cylinder reservoir.

"Quote" Before I installed the repair kit I would have brake one day on the next nothing. I'm going to open it back up tomorrow and also check the caliper.[/QUOTE]

It sounded like bleeder was sucking air before the rebuild.

Day 2 of trying to bleed the brakes and still nothing. Took apart the master cylinder again and made sure no damage from the repair kit. Put it all back together an attempted to bleed the brakes again still no pressure in the handle. I'm at a loss at this point. Going to check te brake line next to make sure there is no damage there for the 2nd time.

So checked the brake line. No leaks and its not collapsed. Now when bleeding with the vacuum I can't pull anything through. I'm at a loss and more frustrated then ever.

Did you secure the lever in half way like Schmitty suggested?

[Cbeck1381]

Yup. Did that, did everything the Clymers manual said to do. The piston in the master cylinder appears to be functioning. I put in a new bleeder valve to eliminate that.
