Brake Line no Longer Connected to Brake Lever

Your brake inner cable has been torn from the head, and the head is either stuck in the lever or has fallen out on the road. You need to buy and fit a replacement inner cable. I'd suggest replacing ...

LBS won't Service Shimano Dual Control Lever

I've successfully destroyed several right-hand levers by attempting to fix them once they've started acting up. One was a broken basket in the shifter, and I forget the actual failure in the others. ...

Replacing hydraulic brake lever

No one can say what you should do, just make a recommendation. Recommended option is to get a new olive and barb, do it right, do it once. If you have problems sourcing these in the time frame before ...

What tool do I need to adjust the brake cable here?

There is more than one way to adjust brake pad "tightness" (I'm assuming this means that the brake pads are too close to the rim). To answer the question. Pictured is the brake cable anchor ...

LBS won't Service Shimano Dual Control Lever

The answer depends a little on the exact model and how deep you need to go. In general the problem is that replacement parts aren't available new if something is broken, and if nothing is broken then ...

How are brake cables installs for drop and flat lever combo brake system?

Nothing special required. The additional brake lever simply moves the housing to actuate the brake while the actual road bike brake lever only pulls the cable. Both actions have the same effect: ...

LBS won't Service Shimano Dual Control Lever

A small addition to this that I don't think has been fully covered: Internal parts for Shimano shifters aren't available. As previously noted, they are also disturbingly difficult to disassemble. This ...

Dia-Compe Gran Compe shot lever - is there a fix for 31.8mm bars?

31.8 is the stem clamp diameter, this is known as oversized. The number that you are concerned with is usually 25.4 or 22.2. Further complicating this is that levers that mount almost up against the ...

Hydraulic brake lever doesn't return after being released, dependent on weather

Long shot: Next time they are acting up, try slightly loosening the lever clamps that attach to the bars. On undersized bars (below 23.8mm standard...) the too tight clamps can squeeze the lever ...

Shigura - Can i use a Shimano XT Lever on A Magura HS33 Hydraulic Rim Brakes

Maybe. Magura strongly suggests using their "Royal Blood" brake fluid, whereas Shimano specifies Mineral Oil. My understanding is that Magura's fluid is a variation of Mineral Oil but they'...

MicroShift R9 derailleurs with Shimano Sora levers

I think, generally speaking, it should work. But what is the worst case scenario? If the Microshift rear derailleur doesn't work well, you would need to obtain a Shimano rear derailleur, any 9sp ...

Front hydraulic brake lever dislodged

Initial thoughts: I see an internal circlip being used in some weird way. These are supposed to sit inside a groove machined inside a bore, and therefore are fully supported by the groove all the way ...

Replacing hydraulic brake lever

New olive - definitely. New insert (barb) - I do not see the point. You won't be able to get the old one off anyway, unless you want to cut the brake hose. Bleed the system from the bottom up.

LBS won't Service Shimano Dual Control Lever

If the tool is the one I'm thinking of, it mainly allows you to take the whole main assembly out of the lever. That assembly is available, at least for some models, as a spare, costing about the same ...

Brake lever suddenly stuck due to an overtightened screw - what went wrong?

Those screws are the "reach adjustment" screws. They control the resting positions of the brake levers, ensuring they're easy to grab regardless of your hand size. Without them, the levers ...

Can i replace just the brake on a bike that has a combined shifter/brake lever unit

I asume you have the complete brake system from you previous bike (Calipers, hoses and levers) In order to complete the installation you would need to buy a set of 3x8 independent shifters, so you ...

What is the actual cable pull of brake levers?

The amount of cable pulled is half the answer to "what is the mechanical advantage of the lever?" The other half is how much did the lever move. This depends upon whether you are using your ...
