help/ advice re: axle

Hello,

I rode my sun solo racing bike (vintage) to work today and when I got there the back brakes stuck on and I couldn't ride it. I took it to a bike shop on the way home and he said the axle had snapped. I haven't got enough money to send it to get fixed so will have to do it myself. If I change the rear wheel will this be ok? Sorry for the stupid question, not much knwoledge of bikes just need it to get to work!

Thank you

Yes changing the wheel will fix the problem since the axle is part of the wheel. Also axles are fairly easy to replace, but you have to match the thread and length.

your bike axles run in a FREEWHEEL ? Wheels Manufacturing sells extra strong axles for freewheels. Measure yours but buy a longer axle than the one you broke. Life is easier that way. And the ends are handy for attaching stuff.

The question is a bit weird.
Axles breaking on fixies / single-speed /externally geared bikes will not cause the rear brake to lock up, that's an entirely different system. Usually won't cause the wheel to lock up either, although it can certain spin poorly.
Coaster, or back-pedal brakes are "never" found on anything worthy of the name "racing bike". But should an axle fail on one of those, it certainly has the potential to cause things to seize.
If it is a coaster-brake rear hub,I wouldn't know where to source a replacement axle. But replacing an axle on a FG / SS / EG bike isn't that difficult - assuming there's someone around who can either supply the axle, or help you figure out the length and the thread.
Replacing a wheel will solve the problem, assuming you're able to pick a near-enough identical one. There's dropout spacing, diameter, brake & drive system and to a lesser degree rim width to match.

Yes, "racing bike" does not really mean anything. A Google search seems to indicate a freewheel equipped bike. The Solo appears to have been a very low level derailleur bike, equipped with bolt-on hubs as far as I could tell, but that does not meant the OP's does not have Q/R. Possible the broken axle caused the wheel to either misalign or wobble, thus causing the brakes to interfere - not really such a thing as "stuck on."

To the OP - If you cannot afford a shop second choice would be a bike co-op where you can get in-person assistance. If not available then Google rear hub overhaul, paying attention 1st to the sheldonbrown and parktool results, then watch videos to see the process. You will need cone wrenches, freewheel tool, and either just an axle or entire axle set. If you need more than an axle the dimensions of the cone are critical. If the cups are damaged the wheel is gone.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

If you can't afford to have shop replace your axle, how is it that you can afford an entire new rear wheel (more expensive)?
Self replacement of axle seems unlikely given lack knowledge and cost of special tools needed.
Really, just have the repair shop do it.
