Re: ????

Not sure on the specifics of setting this up. A booster is $100-$150 IIRC. Somebody who's done this will probaly post shortly.

Re: ????

I just did this and a rebuilt booster from Autozone is $100 but you will need the brackets that mount the booster to the firewall and the linkage to connect the booster to the pedal. I bought a used booster set up off Ebay for about $40 and just used the brackets/linkage. Others have used a 73 and later booster with success but I have never done that. You will need to hook up the booster to full manifold vacuum. Use large nipple at base of carb or use a 90 degree fitting in the intake.

Re: ????

It can be done in one morning assuming you have every part needed already. Juts don't remove the master cylinder or break open the brake lines. Just pull the master away from the firewall and bend the hard lines enough to get the booster in. Also, make sure that the hole in the master cylinder piston is shallow enough to accomodate the new pin coming out of the booster. The pin must not push on that piston in a resting state but also cannot have a lot of slack either.

Re: ????

ok. my brothers girlfriend's dad used to be a mechanic and im going over there tonight so he can help me put on the rear brakes that i have yet to do. so when i'm over there, i'll ask him to help me when i get the parts for all this. cause its not a cool thing when youre going up to a stop sign and youre still rolling and your last resort is pulling the e-brake and sliding for ever. thanks for all your help. im going to keep it all in mind.

Re: ????

Manual drums should not be that bad. If they are, you have other problems and the booster may not fix those maladies. May want to bleed your brakes really good and make sure all the wheel cylinders are dry and you have no fluid or grease on the face of the shoes.

Re: ????

good info, i'd get the drums and shoes in good condition first, bleed the system (totally if you can) and see what you got. I had a 69 with drum brakes and wasn't afraid to slam on them to stop....

Search our parts board for brake booster parts and you can always do that upgrade later. I found that you can buy a booster/MC combo from autozone which only cost about $10 more than the booster alone. Don't trust a used booster though, they can rot inside...

wheel cylinders cost $10 and will require you to pull the brakes apart (no big deal). A leaky cylinder will get fliud on the brakes (BAD!) and cause you to lose braking (VERY BAD!).

If you are unsure about doing them then just take it to a brake shop and have them gone over.. these parts are cheap anyway and your life is worth it!

Re: ????

ok. i changed the front brakes myself cause i know a little about what needs to happen but i dont remember the brakes pads getting anything on them or anything. my uncle told me i might need to get the rotors turned or lathed but i havent done that yet. i would like to do everything myself because thats what i want my career to be when i get old so if worst comes to worst i'll take it to a brake shop and get them to fix it.

Re: ????

did you put new wheel cylinders on as well? If they look wet and greasy then you should... I understand doing it yourself, I can do disc brakes but haven't played with drums much.

BTW you don't have rotors if you have 4 wheel drums... a brake shop can turn the drums to make them round again...

Re: ????

Leaking wheel cylinders will allow all of your brake fluid to literally leak out leaving you with no or little brake fluid, leading to a catastrophic brake failure. Additionally, they will soak the shoes and the shoes will not operate when soaked with brake fluid. You will lose all braking. I know, it happened to me before. Turning the drums will not really solve your problems. Concentrate on bleeding the brakes well and making sure you have no leaks anywhere and be sure the hoses are in good shape and installed correctly with no kinks or pinched off areas.

Re: ????

nice thing about new wheel cylinders (besides being able to brake) is being able to turn the bleed screw without rounding it off!

www.rockauto.com has rears for $5.05 and fronts for $6.35 each. Plus you can find 5% codes online...

true, but then you have to find spindles, 5-lug rims, and pads and rotors and calipers and hoses and prop valve... If you can get on the road safely for $100 or so then you should be good for awhile...

Re: ????

i changed the brake pads for the drums last night. bled the lines and its way better than it was to begin with not as good as it could be but i feel better about driving it now. im not sure i got out all the air out because i still have to pump the brake a little bit but im sure i got almost all of it out. maybe another bleeding would fix it.

Re: ????

There's a lot of good info here, but I think the most important thing is to get the brakes working properly before upgrading. You may find that you stop well enough with properly function manual drums. You may not feel the need to invest in a booster and stuff.
