Re: Brakes are utterly useless--how do I fix them? [1Attachment]
BobHenry, I have a brake pedal assembly, I will sell. Price is $10.00 plus shipping. I can send a pic if you want. Are you looking to replace the master cylinder with a original single reservoir? or a newer double ?For a single, I have drilled hole in the filler cap, tapped it for quarter in. pipe , run a piece tygon tubing? up along the left side dash and capped it off with a fitting To accept a pipe plug. When low, I remove plug and fill with a funnel. The tygon lets me see how full it is. ?I have lots of spare parts from 3 citicars. ? Sent from for Windows 10 ?

Re: Brakes are utterly useless--how do I fix them?
Hi All,
I suspect most of the rust was from the master cylinder--it was full of rusty brake fluid when I got the car. Ill check the brake lines as suggested, though.
The one cylinder I tried to rebuild didn't seem to be rusty inside--I think the leaking may be caused by the rubber that came bent out of shape.
Current plan: - Flush brakes to get all the nasty old brake fluid out
- Gravity-bleed the brakes (might be able to do this at the same time as above)
- Inspect brake lines, hope they're all fine
- Replace rubber on the cylinder that'd leaking
- Bleed brakes some more
Seems like a system this simple shouldn't have so many possible issues, but it is an old car...

I don't know where they got their disc brakes, but around that time I was working on a small prototype car and we used disc brakes that were designed for industrial machinery - stopping lathes and that sort of thing.? We cut our own discs from 1/4" mild steel plate and used those calipers for our 800 pound car, and it worked OK for the load they had to carry.?

The disks about 7 inches around and 1/4 inch thick. They cant take much thermal energy before overheating. Mine deffently cannot. I dont know if they could be used on an aircraft but I would not use them. You can press on that pedal all day but with a single caliper set up, you are looking to break things.

When I adjust my brakes I get them all as close to equal as I can. Then I go make a few stops. If it's pulling a bit I tighten the side it pulls away from a notch or two till it brakes straight. Pedal height will be determined by shoe adjustment. The backs should be adjusted too, but they are annoying since the wheel comes off to do it.?
?
Hi all, thanks for the responses.
I've bled them (of course). They all run free of bubbles (Except the one with the leaking cylinder), but the front brakes still have old rusty fluid in them, so I should probably flush them.
I do have the dual cylinder (thank goodness), so it wasn't hard or expensive to replace.
Bob, if your car has the dual-cylinder system, the master cylinder isn't too hard to find, and I have a part number for it.
Nicholas, I do mean foot to the floor. I don't think the pedal actually touches the floor, but it goes as far as the master cylinder will mechanically allow it.
I tried readjusting the brakes (front only) to be tighter (probably pretty close to 1 rev) and noticed that they drag unevenly.. Is this normal? (I suspect the brake shoes are unevenly worn, since the brakes were (I think) pretty out-of-adjustment when I adjusted them. I do have sources for new shoes (I did a bunch of internet-sleuthing to
find them), but they're still $50 for a set of 4, so I'd like to try
working with the ones I have, first.
Of course, tightening the brakes didn't help any.
I think my next steps will be to flush the lines, maybe just by opening the bleeder on one at a time and letting the reservoir run down (I'll top it off now and then).
I might also order a new set of rubber seals for the rear cylinder that's leaking, and go through taking the axle out and working around it all over again...
For a long term solution, I think I'd like to somehow incorporate rudimentary regenerative or plug braking. Save expensive brake parts, and it would help the braking power of the car a lot.
(Fun fact: If you have a contactor-based system, you're all set up for regenerative braking already. Just stick it in reverse while driving forwards, and apply the accelerator lightly! It worked for me, but I don't think the BMSs on my Li-ion batteries liked it a lot... Don't actually try this, since it's terribly uncontrolled and probably bad for your batteries.)

?
How do you adjust the brakes? Do all the cars have this need? Mine is a 76 with disks in the front. Do you need to adjust disks? Or only the drums. I am a little confused.?

When I adjust my brakes I get them all as close to equal as I can. Then I go make a few stops. If it's pulling a bit I tighten the side it pulls away from a notch or two till it brakes straight. Pedal height will be determined by shoe adjustment. The backs should be adjusted too, but they are annoying since the wheel comes off to do it.?

Hi all, thanks for the responses.
I've bled them (of course). They all run free of bubbles (Except the one with the leaking cylinder), but the front brakes still have old rusty fluid in them, so I should probably flush them.
I do have the dual cylinder (thank goodness), so it wasn't hard or expensive to replace.
Bob, if your car has the dual-cylinder system, the master cylinder isn't too hard to find, and I have a part number for it.
Nicholas, I do mean foot to the floor. I don't think the pedal actually touches the floor, but it goes as far as the master cylinder will mechanically allow it.
I tried readjusting the brakes (front only) to be tighter (probably pretty close to 1 rev) and noticed that they drag unevenly.. Is this normal? (I suspect the brake shoes are unevenly worn, since the brakes were (I think) pretty out-of-adjustment when I adjusted them. I do have sources for new shoes (I did a bunch of internet-sleuthing to
find them), but they're still $50 for a set of 4, so I'd like to try
working with the ones I have, first.
Of course, tightening the brakes didn't help any.
I think my next steps will be to flush the lines, maybe just by opening the bleeder on one at a time and letting the reservoir run down (I'll top it off now and then).
I might also order a new set of rubber seals for the rear cylinder that's leaking, and go through taking the axle out and working around it all over again...
For a long term solution, I think I'd like to somehow incorporate rudimentary regenerative or plug braking. Save expensive brake parts, and it would help the braking power of the car a lot.
(Fun fact: If you have a contactor-based system, you're all set up for regenerative braking already. Just stick it in reverse while driving forwards, and apply the accelerator lightly! It worked for me, but I don't think the BMSs on my Li-ion batteries liked it a lot... Don't actually try this, since it's terribly uncontrolled and probably bad for your batteries.)

Re: Brakes are utterly useless--how do I fix them?
If you have rusty brake fluid then
your cylinders are most likely are pitted and need to be
replaced. I've tried re-kitting honed brake cylinders since the
60's and never been satisfied with the outcome.
Also, I would suspect the lines are
rusted thin at their lowest point where gravity would cause the
water to settle out to. If a screwdriver blade jammed hard
against the bottom of the low part will dent the line it is too
thin to depend on and should be replaced.

Re: Brakes are utterly useless--how do I fix them?
Ha, yeah, when I heard the term "lock them up" I knew something was different. The disks are awful and take forever to stop, they squeal untill you hit a bump that separates them from the disks. And they also burn and fade easily. But the plus is that I dont think you have to adjust them due to the way they work.?

Subject: [C-Car] Brakes are utterly useless--how do I fix them?
When I bought my CCar, the brakes (while they worked) weren't good and I figured they could use some work. Here's what I've done so
far:
-
Replaced the master cylinder. I did bench-bleed it.
-
(tried to) Rebuild the left rear brake cylinder. It was leaking, so I got it new rubber, honed it, and put it back together. It still leaks, but not as bad now... The internal metal piece was
bent out of shape on the new rubber on the side that leaks (Still). I wonder if that it the cause of the leak.
-
I adjusted all the brakes, though I've never done it before. They worked much better afterwards (testing the car at 1-5MPH rolling).
Here's the problem--despite everything I've done, the brakes somehow manage to be
worse than when I bought the car! Other than that leaking cylinder, I don't see anything wrong with the system. The pads and drums should be fine, the car has under 2K on it.
Anyone have any tips for how to get the brakes back to working condition?
(To give an idea of how bad they are: 10MPH, foot down to the floor, and the brakes do
almost nothing. If I was on level ground, I might stop after 20-30 feet.)

Re: Brakes are utterly useless--how do I fix them?
I had to vacuum bleed mine. I couldn't get the air out. Hopefully the master you replaced was a dual one(AMC) not the older single style.? The proportioning valve might be stuck. Mine was too. I had to whack it while my helper was stomping the brakes.? Adjusted properly, my brakes lock the wheels easily. When adjusting brakes, make them tight. Like one revolution or less tight. The drag will work out in a mile. They constantly need adjusting. No self adjusting hardware. I adjust mine monthly, or I run out of pedal before I stop by surprise. Not a great feeling! Start bleeding with the RR,LR,RF,LF.?? After all that, I agree, the brakes do sort of stink. I've been looking at alternatives, with no luck so far.?

When I bought my CCar, the brakes (while they worked) weren't good and I figured they could use some work. Here's what I've done so far:
-
Replaced the master cylinder. I did bench-bleed it.
-
(tried to) Rebuild the left rear brake cylinder. It was leaking, so I got it new rubber, honed it, and put it back together. It still leaks, but not as bad now... The internal metal piece was bent out of shape on the new rubber on the side that leaks (Still).
I wonder if that it the cause of the leak.
-
I adjusted all the brakes, though I've never done it before. They worked much better afterwards (testing the car at 1-5MPH rolling).
Here's the problem--despite everything I've done, the brakes somehow manage to be
worse than when I bought the car! Other than that leaking cylinder, I don't see anything wrong with the system. The pads and drums should be fine, the car has under 2K on it.
Anyone have any tips for how to get the brakes back to working condition?
(To give an idea of how bad they are: 10MPH, foot down to the floor, and the brakes do
almost nothing. If I was on level ground, I might stop after 20-30 feet.)
