Front brake lever travel

<< < (3/4) > >>

K2-K6:
I feel that there could be elements of many previous posts that will be affecting it.

The lever travel is linked to how soon the passage into the reservoir is closed off during lever stroke.  As Steff says,  if you squeezed the original quickly enough you'd get a little feedback visible with the cap open.  Once that locks off completely the line pressure then builds properly,  if this is a soft close it will give you more lever travel.

My recall of K2 and K6 was that the lever was quite soft and would probably go to about half travel if set up well.

But of the F1 it seemed more dead and harder to get lever travel.  Whether it changed spec between the two I've no idea.  But if it did and the pattern part is F1 based,  then it could account for some differences in feel and travel.
Or just that the pattern part doesn't quite replicate the internal geometry of an original.

An original master with refurbished seals may give you a different feel.

I pumped the lines hard, and couldn’t detect any ballooning at all. Given the hoses are only 5yo / no bad weather / low mileage / adorned / moly coddled etc I can’t really believe they’re failing. Dang... and maybe an evening on eBay, though who knows what you’d be buying.

I did say there would be no bulging of the hoses caused by this type of fault in a hose. Maybe I should have stated even under pressure.  :)

My recent experience of the DS pads is that they offer low levels of bite. I replaced my pads with EBC V pads (semi sintered) at about £25 a pair. Much better bite almost immediately after fitting.

Have you a link Rob for them in the UK...I can find them in germany?
