Brake problem

James Dalton said:

I have a Cervelo Dual 10 and love it.

One problem is that the rear brake is hard to pull on and feels like the cable is grabbing somewhere along the routing. The caliper does not spring back open and the cable goes limp in the brake lever itself.

Anyone know how to fix this?

Clean and lube everything (brake pivots especially) and check for kinking or twisting of the cable run before you replace something that is not broken.

I have just discovered a similar problem with my rear brake: Brake lever feels 'grabby' & caliper is not fully opening. It's just the last little bit of return.

I have lubed everything but no improvement.

I should note that my bike only has about 1,000km on it (Shimano 105). However, the last 300 or so have been done in the Irish winter. My rear brake gets covered in lots of '****' on every rideb & there is no local bike shop where I live in Cavan.

It feels to me that the sticking seems to be coming from the cable going through the housing from the lever, because when I pull the cable by hand the brake fully returns.

Any help will be appreciated.

I had the exact braking problem last fall. Replacing the cables corrected the issue. When I removed the cable from the housing I was surprised how much grime was on the cable. I think the problem for me is the sweat that runs into the housing. I live in SE Texas and summer riding will dehydrate the body fast.
