Is it possible to convert rear drum brake to disc brake on PCX scooter?

Recommended Posts

Is it possible to convert the rear drum brake to a disc brake on a PCX 150? Do they sell drum-brake to disc-brake conversion kits?

I know it's a relatively easy procedure for a car, I'm hoping it's the same for this scooter.

Never seen it done...is it possible ? yes with a big amount of "faffing" around with custom made bits and bobs...the big question though is why ?

Use the front disk brake for 75% braking and the back brake for the rest...

Most of our students have accidents because they're not aware that using the front brake in rain is causing them to crash.

 

Using the front brake to 75 % on sand will also knock you down.

 

IMO, a healthy mix of both  brakes should usually do the trick. Perhaps there are some better brake shoes out there? 

 

   I don't think it's easily possible to convert such a wheel into a disc brake. You'd need plenty of modifications that might not even fit on these bikes.

Yes of course I should have said 75 % front brake in the dry, no sand and straight roads...more back brake employment in the wet,sand or when cornering ..note that braking in a corner is not advisable ,all braking should be done before entering the corner but if you have to brake in a corner then back brake is the better option as a rear wheel skid is easier to recover from, a front wheel skid in a corner almost always will be disastrous.

Dunno but a well maintained rear drum will lock up the rear wheel and so why bother with disc conversion especially on a scoot.

I agree, why bother. During heavy breaking a lot of the weight is on the front wheel anyway. 

 

My old first gen 150cc pcx have been fine, nothing to complain about, including the brakes. It got dual brake system as well.

 

Does the latest pcx have ABS in Thailand?

It seems on most bikes the original brakes fit the needs. On front wheels they need to be stronger than on the rear. 
I am pretty sure the original PCX brake will do the job.

What do you expect from a rear disc brake? Better braking? Faster stopping? I have my doubts.

The Honda PCX sold in Indonesia has a rear disk brake and ABS. Maybe the parts from that version would fit the Thai version.

Right-on!

This Indonesian PCX - ABS version is exactly what I'm looking for!

I am looking for ways to avoid the possibility of wheel lock-ups on my PCX because I personally don't cherish the thought of being thrown off a scooter.
I began this thread by asking whether a disc brake could replace the rear drum brake on my PCX. My ultimate goal is to install dual ABS. Now that I know the PCX ABS model is sold in Indonesia, I now have to find out if, (1), the F/R ABS hdwr, all the rear disc components - wheel and hub, disc and hdwr, etc. - are interchangeable with my 2015 model. If so, (2), would it be easy to get the Indonesian parts shipped to LOS - exorbitant import custom fees?

What gave me away? 🕵️‍♀️

Yes I am a noob and looking to have the protection of ABS. Thanks for those braking tips! 👌

Don't grab the brake lever so hard?

A conversion kit per se, is no longer required because Issanman's post presents ~ 90% solution: The Indonesian PCX mfg plant already produces a dual disc - ABS PCX model.

Besides installing the physical hardware, is there a more difficult step to converting a non-ABS to ABS? Some type of logic controller system? Could this be a stand-alone unit? 
The reason I have not bought a different scooter is because there is no other 150cc auto scooter sold in LOS that has dual disc brakes and ABS that also suits my personal tastes.
