Hi everyone, Rebuilt my master cylinder and checked the shop manual regarding brake bleeding. Took out the dust screw. Manual says to install bleeder. No one has one that will fit in the dust screw hole. Where can I buy one or is there another method I can use? Also the car has been up on stands for 2 months. Today I found that I can not turn the steering wheel. Something is binding. I did no work to the steering or suspension, other than removing surface rust and painting. Could the binding be caused due to spring sag? I don't see anything on the suspension hitting anything and everything work smoothly before. Any help on either issue would be greatly appreciated.

Macs and probably other suppliers sell replacement bleeder screws that a hose will slip on to. as for the steering problem, my best guess is steering box or a problem with the ignition/steering lock.If you have or can borrow a tie rod tool [pickle fork] take the drag link loose from the pitman arm and see if that frees up the steering.

If the suspension is just hanging put a jack under the axle and lift the axle and then try the steering.

Thanks guys for the quick responses. Steering is ok. Bad day dealing with my brake issues and forgot about the steering lock. Duh. I looked up the bleeder screws on Macs.My bleeder screws work ok. Take out the little screw turn the bleeder screw and fluid comes out. I guess I should have asked - How does a bleeder hose fit on it? There is a picture of what I think I need in MACS catalog but it looks like it is for trucks. Page 13. Sorry for the confusion, but before this car the oldest one I worked on was a 51 Ford coupe and it had all the "standard" stuff I'm use to, ie bleeder valves on the back plate and a master cylinder on the firewall:) SO this car is a learning experience, as well as, a humbling experience.

Hello. glad to hear you didn't have a steering problem. As for brake bleeding, back in the day you could buy a special bleeder hose from most any parts store with a metal fitting that scr*w*d into the hole in the bleeder screw. I don't see anything like that in the Mac's catalog. You can bleed the brakes without it, but it sure makes a mess. Look again at the Mac's catalog. They have bleeder screws like yours, and another type that you can push a hose directly on to.

You can buy a brake bleeder kit from NAPA http://www.napaonline.com/napa/en/p/BK_7769038 or you can go to the hardware store and buy a piece of plastic 1/4" id tubing to slip over the bleeder screw and reach into a container with enough brake fluid to keep air out of the tubing while bleeding the brakes.

Thanks for the website, Tom. I'll contact them and Macs. In the meantime I found that the thread diameter of the dust screw which goes into the bleeder valve is 3/16ths. Bought a piece of hose and it fits tightly. Think I'll try that also. Right now I have to get another car ready for a show tomorrow. Thanks again to all of you for your help. Can hardly wait to drive the car now that the weather is getting warmer and I'll be able to stop too:)

The dust screw must be removed in order to bleed the brakes. The bleeder screw is 1/4" on the OD where the bleeder hose should go. Forcing the hose into the dust screw opening is not advisable, it may pop out the first time you open the bleeder screw. See the picture on this web site http://www.cargurus.com/Cars/Discussion-t1086_ds673996
