Disc brake to drum

[Revvers]

I have a Scoot Rs inboard disc brake and I’ve never really been happy with it. After looking at a few options, I’m considering taking it back to the drum brake it had originally. The thing is, I had disc links welded to the forks. Can I convert back to drums, or is it too much of a faff??

I ma struggling to comprehend wat you have done. Welded the disc links to the forks??

That would stop the front suspension from working.

Sorry, I’m not good with this! I originally had a drum brake and changed to an inboard front disc. Can I just change back to a drum brake easily? It was fitted when I had a respray so I didn’t do it myself. Hope that makes sense!

My Jet 200 had a disc brake, not brilliant. My GP150 has a drum brake, stops on a sixpence.

This depends if your disk brake was designed for disk links or drum links.

If there is a U shaped moulding on the brake back plate - offside and a corresponding pin in the brake side of the fork link then you have drum links and could easily change back to a drum brake.

If there is a large stud sticking out of the backplate which fits in a U shaped moulding on the fork link then you have disk links and you would need to change the links to fit a drum brake.

Since you had some thing welded do you mean you had studs added to the links to fit dampers? This is the only common modification in that are that needs welding.

That was what I had welded, disc links. I don’t think I worded that well! I’ve decided that I’m going to give the reverse pull set up a go first, before any more expensive work

Sorry you've really not made that any clearer - could you possibly post a picture of the off side front / rear of your brake and links?

Not having had a scoot rs standard disc I can’t comment. But I know 2 people who’ve changed the actuator to a original Italian (stronger spring probably) and found them to be a whole lot better. I currently run a reverse pull original disc and I’m really happy with how it works. I had a hydraulic backplate on standby , I ain’t going to need it I don’t think.
So keep your eye out for an Italian actuator and reverse pull. There’s also a larger diameter front brake cable available which will help improve.

Good look.

Those are 100% drum links - you could slot a drum brake straight back in but I'd try the suggestion about the actuator first.

[Revvers]

I do have the stronger actuator after asking about this a couple of years ago. I’m going to try the reverse pull, but I think I will start looking for a replacement drum hub and parts. Thanks for all your help

Sounds like you had damper studs welded to the links.

I've got a drum on my S2 which is an Indian hub and have reverse pulled it and its good, same with a Spanish one on my jet/sx.

When you do the reverse pull use new shoes, thick inner cable and keep an eye on the shoes' unlikely but dont let them get heavily worn down.

I prefer the well set up drum over the outboard hydraulic disc on my GP

If you have the stronger actuator try the thicker brake cable. Setup up correctly you don’t be disappointed. I’ve got sintered pads in which I filed so they can move and copperslipped the back. Sintered on my inboard hydraulic squealed at low speed ok at high speed. But never had that issue with the reverse pull setup. Good luck.

Will a thicker front brake cable fit an Italian headset set up?

Also anyone got a pic of drum reverse pull?

Cheers

[Storkfoot]

Hard to see but this is on one of my old GPs.



Have a read of this thread too.

Couldnt agree with you more - I always double check prices of everything including postage now.

- Bought 5 items on one order last year - saved myself £35 on an order total of £140
- Bought an RT kit last year - asked one seller at custom show could he move on price - catagorical No - walked outside and bought on line and saved myself £50.
