Rear Brake Sticks On

Recommended Posts

Right, when i last had my bike i was rear ended by a drunk driver and i ended up making a claim. I've now got the bike back and as soon as i initiate the rear brake, it seizes on but the pedal comes back up with no issue, also i noticed that the case for the shoes (the drum) gets extremely hot.


I checked it over and cant physically see any damage apart from the fact that the rear brake arm sticks on and has to be manually reset.


If you need any more information please let me know, the bike is a Lifan Arizona (yes Chinese...i know...)


Thanks guys for any help you can give!

Hello and welcome . When you say you have checked it do you mean that you have taken it completely apart and cleaned, inspected and lubricated all the components ? Have you tried adjusting the pull rod ? If you do this it should be fairly easy to see what's causing the problem and equally easy to fix it . If you are really stuck, some pictures would be helpful. Good luck.

1. You have just 'got the bike back' - Return it to the repair shop and say 'fix it'.


2. As bob says, the mechanism is quite simple so, strip, clean, check, re-assemble.


3. The issue 'could be':


a) bent shaft (from link to inside the drum)

b) dirt / gunge inside the drum

c) bent pull rod / damaged return spring


The 'heat' will be caused by the binding brake shoes - Keep this as is and you will soon wear them out!


:cheers:

Hello? Isn't this just a teeny-weeny clue as to what's going on? Why is it sticking?


Have fun.

I'm beginning to think that people are living in some kind of virtual world where the first impulse is to reach for a keyboard instead of the spanners . Whatever happened to the idea of taking something apart , figuring out how it works , giving it a tap with a hammer or a dab of grease and putting it back together again ?

Hello and welcome. Might be worth getting a Haynes manual and having a look yourself. But if it was repaired by a garage following the crash then you must take it back to them to sort out. Also tell your insurance company that it wasn't fixed correctly.

Well, that would be what us old farts would call "common sense".


To the OP - hope you're having fun already - but if not, remove the rear wheel AND TAKE THE BLOODY HUB APART. It ain't a difficult job - just don't breathe the dust that will be found inside. Brake cleaner and rags are your friend.


If anything is bent, or otherwise sexually intercoursed, it will be obvious. Is the brake actuating cam going overcentre when you step on the pedal? This would make the brake "stick on". It could be as simple as the brake arm pivot needing a quick rub with fine emery paper and a SMEAR - no more - of high temperature grease. You will notice if the bearing is unduly stiff when you have taken it apart. But if you're not happy working on your brakes, take it to a shop.


Remember kids, safety first!

We were all Newbies with regards to bike maintenance and repairs once......what now seems obvious to us at one time wasn't. ......so let's just try to be helpful, eh? :roll:

 

That's a fair comment but what is beginning to get annoying is that in many cases like this the OP makes one post without reading the suggested requirements and then is never heard from again . Most of the advice given here is good advice . It's a simple mechanism that anyone ought to be able to understand if they made a little effort .

Hi Tango - see where you're coming from, but I seem to recall that the way most of us learned was to buy the book, read the book, try to understand the book.......and then get the tools out. If you don't understand how something works, then you will never learn how to repair it. And taking things apart - and putting them back together again afterwards - is one of the best ways that I know of learnng how to understand something.

Or borrow it from the library if you're tight fisted like me ! My genuine manual is a free PDF on my phone.

I know what you're saying mate.....but some people do just make one post and we never hear from them again.....it's just the way it is unfortunately.

Yeah, I learnt from books and mates......mainly because the Internet didn't exist back then...... :wink: I'm an engineer, so I have a natural aptitude for this sort of thing, but some people are not blessed with this skill.....but maybe with a bit of help they can develop the skills......A Haynes manual can only teach you so much..... :wink:

perhaps the OP is looking at the replies without logging in.

 

Very good point, and if he has followed Grumpy's and Speedy's advice and got stuck in as recommended by others then he's probably been riding around all week and has forgotten the whole thing.

Shouldn't that read " I have a natural aptitude for this sort of thing , so I'm an engineer" ? 😉🔩🛠
