Mighty Norton Knowledgeable,

I have a Brembo master cylinder with a standard Lockheed brake.

I'm wondering if any of you can make a recommendation on a good Vacuum Pump that both extracts and pushes fluid?

I need to completely bleed and re-fill my front brake and based on the CNW manual i need to push fluid through the Lockheed into the master cylinder and then bleed the old fashioned way.

Your suggestions are appreciated.

Thanks!
 
The MITYVAC is a good quality kit, but probably not worth investing in to bleed one brake
 
From your post you're here in the States. Try Harbor Freight for a cheap knock-off. I got mine there when all they carried was one but it was still pretty cheap. Last time I was there the vacs were even cheaper. Check on line. Mine has worked great and has a number of accessory fittings for cars and such. I even saw a brass one last time. They've kind of become generic. I should have mentioned that these pumps can either pressure the system or put a vacum on the system. On mine it's just a matter of which way the hoses are hooked up. Lots of versatility with them.
 
I was wondering this same thing....

I've seen a ton of different kinds of vacuum pumps and vacuum pump kits online, but the specs never say whether they are push/pull or just pull. Even the ones I've seen in auto stores don't tell you, so this is a great question.
 
I always just drop by the pharmacy for a large syringe. When it gets dirty I thow it away and buy another one. Get the one with the plastic seal built right on the end of the plunger instead of the rubber seal so oil won't affect it. James
 
So i found an easier solution then buying a bleed kit!

I hooked up a long plastic tube to the nipple. Filled it with brake fluid. Then used a small air compressor to push the fluid into the caliper and up into the master cylinder.

Bleed, Repeat, Bleed Repeat until all the air is out and the brake level is nice and firm. I'm very proud of myself (no mechanical skills or ecperience).

Lloyd,

Nashville is great. Cold right now but still haven't had to park the bike. It will be in the 50's again later this week! More riding. Super fun town.
How's michigan? Did you go to the Norton Owners Christmas Party?
 
Ive never tried this on a Norton, but my BMW ABS needed bleeding and the only way to successfully do it was to pressure bleed it. I had tried vacuum, but no go on the ABS system. I affixed a nipple to a sacrificial reservoir cover and used a small weed sprayer filled with a pint of brake fluid . Worked slicker than snot.

Michigan is freaking cold, single digits when I took my bike to the IMS in Novi . I think I got wasted on New Castle at the party :mrgreen:
 
Go to veterinary supply store, buy a very large syringe and some tubing and your done for about $12. I've been bleeding disc brakes on mountain bikes like that for years and I'll do the same with my CNW brake kits.
 
I haven't done it for years but on medium trucks I used to use an electric fuel pump. It was hard to bleed hydraulic brake boosters in the middle of the frame.
