the feel is great,but it will not do "stoppies!!"
the pads are ok,but feel quite "hard",
does anyone one know a grippy pad?
something softer,we don't want to wear the disc,and as we tend to do small mileage,a high wear rate is ok,
any ideas ?
I am using DSS cheepo pads

Did consider another disc but from what I've read it sounds a bit tricky finding the correct parts? I'm not under any illusions concerning the performance of a 40 year old bike and ride quite sedately but you can't allow for someone pulling out of a junction unless you ride every where at walking speed.U need to find a disc and caliper.i used a goldwing MC from Dave Silvers £40.it looks the same only a little taller.Braided hoses will also help

After getting off my street triple and straight on the 550 it really brought it home how poor the front brake is on the Honda. Are they meant to be this bad? Or could mine be not as effective as it should be? I would say the rear brake has almost as much stopping power and that it would probably be impossible to lock the front on anything but a wet greasy surface. Am sure the front disc on my rd250 was much better back in the day,admittedly the yamaha was a good bit lighter. As far as I know the pads are quite new and the travel at the lever feels fine.I do understand this cos i also have a street triple and the brakes are awesome

However, in the bikes defence, I think it has a lot to do with feel as well. For me, it was worth conducting a test just to see what the stopping distance was. On a very quiet road near my house there is a straight bit which is about a mile long. About half way along I placed a stick in the verge, turned round, went back up the road before setting off again. I accelerated up to 60mph and rode to the stick marker, whereupon, making sure no one around, I slammed on the brakes as hard as I could and came to a stop. I have to say the result was much better than I had thought possible. Although it feels like the brakes aren't doing much the stopping distance is quiet respectable.
As with all equipment on the bike, make sure it is well maintained. Make sure the caliper is in good order, strip and clean, replace seals, bleed correctly, fit new pads (the ones from Dave Silver are the best I've had), adjust correctly, use a braided hose etc...etc...

Is the pivot seized
Do the hoses bulge
Are the pads seized in the caliper
Are the pads contaminated
Are the pads bedded in
I've had the pivot seize twice and it makes a noticeable difference, it's worth cleaning it every service.

It might be worth checking a few basics before modifying.

Agree with totty 100% rough up the pads and disk and degrease it makes a massive difference.
Thee pivot also has to be perfect.
The brakes aren't actually that bad there's just a lack of feel at the leaver you've just got to remember your on a 70's bike.

Might look at gathering the bits and pieces for a twin disc set up. Previous owner obviously thought the same about the brake perfomance as the ******* advertised some parts for a twin disc conversion on here a week after I had bought it rather than throw them in with the bike. Think they turned out to be wrong anyway!It was me that bought it!
Yea u r correct,the caliper was for a 750

With a seized pivot it's like having half a brake - not good. I always keep it greased up with copperslip.I may be wrong, but I thought Copperslip is intended to be used for assembling items which when in service do not move relative
to one another. It is not a lubricant but an anti-seize compound. Earlier this year I recall Julie had a problem with a worn pivot
which she put down to being due to a previous owner having used copper grease on the pivot. I would use 'normal' grease for this.
Agree that a seized pivot is not good - I have had that problem in the past.

Brakes well and no squeaky brakes to date.
My experience with copper grease and brakes is never good overtime the grease dries out and goes hard causing the brakes to stick.
I have rebuilt my callipers on my truck and used copper grease on one side and corrosion block on the other almost a year on the side I used copper grease on has just started to bind where as the other side is still good.
