Hi,
Ive just fitted a hope m4 (the old style silver one, not a mono or a tech)to my bike, and although it grabs really well and works A1, there is a lot of travel on the lever and it nearly goes back to the bar before it bites properly. Theyve just been bled by the previous owner and theyve got brand new pads. Ive fitted an alligator rotor.
Is there any way of adjusting this so that the lever engages sooner and doesnt need to be pulled in so far, or will i just have to get used to it?
Don't think there is any scientific way of adjusting it but if you drop the wheel out and squeeze the lever a bit, the pads will move inwards...replace wheel and the throw on the lever will be reduced - it does mean the pads are closer to the rotor so may rub but it does effectively reset the 'home' position of the pads/pistons to help reduce the amount of throw.
Nice one, thanks for that. I`ll try it tomorrow.
Is there not a push rod from the master cylinder to the lever which you can screw in or out to adjust the "bite point" of the lever?
bigyin, that adjusts reach not bite. do as dick barton says +1

bigyinn, thanks for trying to help though, i`ll remember about that pushrod if i do want to adjust the reach. jedi, what dick says makes perfect sense to me, so im going to take your advice and give it a go tomorrow. thanks folks.
If they've been bled correctly and you still have long lever travel, then your caliper is probably in need of a strip, clean and lube with silicone grease, this should bring the lever travel back to a sensible amount.
From my dealings with Hopes this seems to be one of their main failings, mainly with the older "basic" lever types.
Oh and I get the idea thanks Jedi! What are you? My other half?? 😆
only on friday nights 🙂 🙂
Ssshhh! 😉
If you attach a syringe full of dot ( no air bubbles ) to the bleed nipple, open the bleed nipple, pump in fluid till you get the desired feel at the lever then close nipple that'll do the trick. If you do it the dick barton way it leaves space in the res for the fluid to make its way back in, and you're back where you started
