V-brakes

I've just replaced the brakes on my Giant Escape 0 with Shimano Alivio BR-T4000s. They seem to be working well at the moment but I'm concerned that the wee pin on the brake only goes half-way into the middle hole of the boss(?). Can you foresee potential danger of the pin perishing early due to its shallow penetration?

Sorry if my terminology is inaccurate.

The wee pin is connected to rear of the brake, below the mounting bolt. It inserts into one of three holes on the boss.

I believe you're talking about the leg of the brake return spring. It doesn't have to go all the way in as long as it's in far enough to stay put, as it probably is. In use, that leg doesn't move, only the one attached to the arm.

The worst that can happen is that it does slip out, causing that arm to drag and slow you down. You can then disengage the brake and ride home carefully depending on the other, but I'll bet it never comes to that.

I'm sorry now I didn't buy the original Tektro brakes.

Purely out of curiosity, why?

Because with the Tektro (which I've had for 8 years) any doubt would have been erased.

8 years from now, after nothing has happened, will you finally be comfortable with these?

Or, consider taking that side out, making sure the hole is clean, and reassembling while trying to guide the leg deeper with the side of a screwdriver blade.

Obviously, not seeing the bike, I can't know, but if it the leg is engaged halfway or so, you're good.

Sometimes you really don't want to know how the sausage is made.

I'd be 73 years old then, just being grateful to be alive let alone still cycling.

I'm a bit more content tonight having taken off one of the brakes - the pin's about 66% of the way in. I've found the depth of the ridge (see image) is less than the depth of the replaced Tektro brake thus causing the whole issue.

I noticed that for the first time today when fitting and balancing the brakes.

The plastic housing that holds the spring in place on some brake models is a lot more likely to break than that wee pin. Your Shimano brakes don't use plastic. You made a good choice.

Excellent confirmation - thank you.
