Topic: Help wanted for conversion from front disc brake to drum brake

[yd72]

I am thinking of converting my cb350f into drum brake.
I read that gt750 can be used for converting into drum brake for this bike.
Anybody has any idea where can I find this set up, any website recommedation?

Or any other set up that is suitable for my bike that is not too costly.
I am in for all ideas and recommendations.

why would you want to go from a front disc to a drum???

[Bob550four]

I have to agree.  going to drum is madness.

[736cc]

   You may consider that a used GT750 J model dual front brake drum set-up on ebay will fetch over $500

The guy I bought my 350f from put a drum brake from a cb350 twin on it to make it look "more vintage".  It works ok but I will be putting the original setup back on sooner or later.  If you want I can take some pics of it this weekend.

Like 736cc said.....a pre 1973 GT750 drum brake is gonna cost you some money. I've seen one's that look like they were sitting at the bottom of a lake for 20 years.....end up selling for several hundred dollars.

If all you want is a drum brake.....find a 1972 Honda CB350 K4 twin. That 2LS drum front wheel will bolt right up to your CB350F forks with no mods. Make sure you get all the hardware like the brake stay...etc. Also....your gonna have to swap out your front brake lever/switch housing.

Hope this helps,
Greg

You guys should maybe trade..

See if you can get a front end off a CB360 twin...around I think a 1974 or so ( don't understand the logic of going to a drum brake, but to each his own  )

I have seen a lot of cb350 twin racers use the Suzuki T500 front drum. The only issue is that after a couple of seasons of hard racing the hubs begin to crack. For street riding however I doubt you are ever pushing it hard enough to make cracking an issue.

Unless you need the drum for a racing class (WERA and AHRMA both have classes where the 350 would be eligible but has to run a drum), going to a front drum for looks is pretty dumb. Plus the 350F doesn't really go fast enough to overpower that front disc.

While a drum does have more overall stopping power than a disc, the advantage the discs had was control and reliability. With a drum you have cable stretch, brake dust buildup, and a variety of factors that make the stopping experience different every time you pull the lever. With a hydraulic disc setup, you have a lot more consistency.

On my track bike, I used the 2LS front drum from a DOHC CB450.  I believe it is slightly larger than the CB350/CB360 drum.  Works fine.

[pablo78cb550]

just go out and get yourself one of these.

[yd72]

Hi all, thanks for all the replys, suggests pls come in.

I have own the bike for 7 years, so I was thinking of going for something different and vintage kind of look. I know disc and drum have its pros and cons. In my country we dont have much resources in either vintage or classic bikes, you dont see many classic bikes here. Finding parts here is an impossible task.

I need more suggests and sources. Keep coming man.........

Is ebay not available where you are living? 

[pablo78cb550]

I drove two hours to get that little '78 red devil.
5700 miles on the clock
and clean.
There are always things around you, relatively speaking.
