Back to front brake system - CB550 (Pix)

[Shooter]

Here is what I am thinking of doing - putting my forks on back to front and running the callipers and rotor on the right hand side ( instead of the left).

Pictures show a Honda (Post Classic Racer) with this treatment and the front brakes work brilliantly. Theory is that the callipers at the back of the fork are more effective. This is combined with braided lines of course. The lever action is solid and effective. The racer has no stop light "switch" and I need to solve this issue - maybe the original presure sensor but in I am trying to achieve a one piece braided line direct to the calliper without the steel hose at the bottom. This is not necessarey if the callipers are on trhe right.

By the way this is very easy mechanically to turn the forks around like this. Nothing to it in fact. I dont even have to turn the tyre around for correct rotation ( I hope)

Excuse pix quality - came off my cellphone camera!

It has dawned on me that I may have speedo issues with this mod. :-\

If I recall correctly, the benefit associated with this modification is the centre of gravity change, not braking effectiveness.

There should be no change to the braking power with the caliper at this or any other position on the rotor.

Whats your thoughts on the speedo?

It is going to be turning around the wrong way if on the other side - isn't it?

"Gee officer... I was only going minus 85mph" :

I like this mod because it also cleans up appearance at the front of the fork.

I honestly don't know what the speedo will do in this case or what others have done to resolve any issues. Maybe thats why you see it on race bikes.

Good point about the speedo!these hubs and front ends can be set up for dual disc,so now keep the speedo drive on the left,and bolt the disc to the right side,aligning the right disc is what you'll have to figure out.Find a master with a smaller bore and a pressure switch,that stock brake is okay at best(it's shite) another way would be to go back the original housing and switch(lower triple)and make up some new hoses($$$$) and as the Tin man says, your locating the weight of the calipers BEHIND the centre line of the front forks

Loco Leon will know how to do what you need to do.

Thing about race bike is no (standard) speedo set up and no stop light (trigger)

I will take a closer look at the dual rotor situation. If thats the case...obviously the speedo thing is overcomeable some how.

Maybe I can put the speedo hub on the same side as the rotor?????

Come in anytime Noel.

The wheel stays the same, the forks are swapped from side to side. You would need a dual disc speedo drive plate as the speedo and disc will be on the same side of the wheel, or you would need to alter the stock drive plate to work with the brake disc(or bore the disc to work with the current speedo drive). Now would be the perfect time top put dual disc brakes on the bike.

Thanx - I worked out the speedo issue from the various advices etc ...and then another arose!

I am running front guards and I then get the issue of an off set guard because the guard is set up to run a hose thru on the left.

Decided: I am going without reversing the forks at the moment and just braiding the lines etc. I have already fitted a new MC kit.

Yep.. Theres your answer...
Ive put dual discs on my cb750 but not actually swapped the forks so that the calipers are in the back of the forks.
Personally, I like the look of the calipers in front of the forks w. the dual rotors... It just looks different...

If your still struggling with the brake switch issue Goodridge(one of the braided line suppliers ) also sells a banjo bolt with built in pressure switch. 22$

I will look into that - thanx for info ...even though it is 48 hours too late for me, because I just had braided lines made using the original sensor. I fitted it all back together a couple of days ago and it works fine bu I suspect the old sensor still contributes a little to a very slightly soft lever action. IN the racer I pictured above... the braids are direct single piece with no sensor and are solid feeling.

I also downloaded the catalogues from the site and could not find the device. Any more clues please?

The trick set up in the 70's was to swing to the calipers rear of the front axle! and it wasn't for looks,it made the the bike handle better,,,,,,,
