Front brake!
Yoshi823:
A friend had a similar problem with his CB500K. Somebody had rebuilt the front end incorrectly & bolted the front mudguard stay between the upper caliper mount that locates the top of the pivot pin, thus misaligning the caliper mounting bracket. Once the upper mount had been placed between the fork leg & the mudguard stay the caliper bracket was realigned perfectly & the fixed pad had full contact with the disc.
Just a thought...

All
Thanks for the replies and advice-
You are correct in that I have replaced the pads- as the ones fitted were glazed (and the brake was crap..)
Before writing the 'Help'- I put the old 'moving' pad back in and that seemed to solve the problem-ie, the brake didnt drag- so I think a strip and re-build this w/end is in order.
The final advice regarding the mudguard- yes, Ive replaced the mudguard when I refurbished and painted the forks- Ill have a look if I can understand what you are sayong to see if Ive put something back on wrong. The pivot is obviously free- as I said, Ive stripped and re-built.
Ive had 2 400/4s and ive never had good brakes on them!
My 2001 R1 is a bit spongy know , but by golly-stops on a sixpence and my daily hack- a GS1200 Bmw has excellent stopping power- it needs to, as I do 30k a year on it!
Thanks a lot all!

I also had a spongey front brake on my 2k R1, so I replaced the standard master cylinder with a radial Brembo one, Ferodo Supersport pads, pistons from a '01/'02 R1 front calipers & Aeroquip hoses. Now, if i'm not careful, I could be thrown over the handlebars if I were to sneeze while braking.
The R1 master cylinder went onto the Exup1000 after a clean & rebuild.

Thats my bike! except mines original, apart from the mirrors! Ive dinged my exhaust twice now and still managed to get a replacement- once when it was someone elses fault and the other when I dropped it- BNIB

I have a noisey pipe but I prefer the OEM item. I heard that plod were down at the Oakdene & they did anybody with a noisey pipe, dark visor or small number plate. My R1 is very standard as I don't need the aggro.
