Technical Drum brakes stuck on

Hi,

my front drivers side brake is stuck partially on. Drum brakes and it is a 1963 chevrolet impala RHD. i took the wheel off and turned the drum it grabs pretty harsh in the same spot.
thinkin the return spring could be weak? any suggestions would be great.
thanks

 

If the drum rotates part way and then it grabs, the drum is out of round, for one thing....might see if you can get the drum turned and see how it does. Be sure to measure diameter first and see if it's still useable, they didn't publish specs back then but I'd not try to get it turned if it's bigger than 11.060" now, and not use it at all if it's bigger than 11.090"

 

I had a shoe that came un glued that grabbed

 

I had a shoe that grabbed and I came unglued.

 

I had a shoe that got leaked on by a little brake fluid and it grabbed like heck.

And I still haven't figured out what side of the car you mean. Why don't people just say "left front" or "right front"?

 

Another cause for it to be grabbing the same spot could be rust on the inside of the drum.

 

@Beanscoot your left or mine?

 

Is this a driven car or something that's been parked up? It can have a bearing (no pun intended).

Could be a wheel cylinder or an old deteriorated brake line to it keeping the brakes partially engaged.

 

Check the backing plates!!!!
The backing plates have pads that the edge shoes slide on and these should be greased. Most owners never greased these and over the years the edge of the shoe would wear a groove due to vibration. Eventually these grooves will catch the shoe causing it to "stick". The solution is to file/polish the grooves smooth if lightly grooved or weld up the grooves and restore the pad surface if the damage is severe.

 

A bad rubber brake hose will keep a brake from releasing.

 

I come unglued every time I ask a transport customer with a Non-Op that has been sitting...Does it roll freely? They always say Yes! When I show up, I find the drum brakes are locked up!

God Bless

If you're unfamiliar with drum brakes, check out a shop manual or youtube. Here's a pic of 63 vette front drums, the parts and layout should be same

I agree with comments above, wheel cylinder / brake hose / brake ***y locking up due to corrosion / warped drum/ damaged shoe. Lot to chase down. Learn about these brake systems to identify it.

If it just started happening - you know the right parts are there. If you just got the car - don't trust the previous mechanic

 

I'm going with the rubber brake hose. replace it.

 

That's a pretty broad question, why not go one step further and pull the drum and see what's going on inside.

 

Try disconnecting or at least loosening the brake hose at the wheel cylinder on the offending wheel. If the hose has failed, this should release any trapped pressure to the wheel cylinder.

 

Old flexible brake hoses can collapse under pressure and when the brake pedal is released the hose can still holds pressure, I they have never been replaced they are 60 years old. HRP

 

As several above have said, Rubber hose's break down over age, Think harding of the arteries...
Free up, spin fine, Hit pedal, No turn..
Cha-Ching, you'll know

 

Rich B ,
That’s a really funny question,,,,!
This is the same guy that asked about his transmission not shifting correctly .
His linkage was hanging down out if sorts,,,,,but he wouldn’t climb under the car to investigate,,,,that went on for two months,,,,lol .

This brake drum will be 6 weeks at least !
