Brakes - which is liked better?

[T4tomo]

The most important piece in any braking system is the tyre gripping the road / *insert non road surface here

how the bike slows the wheel rotation down is less important.

More than that. You have to drop wheel out, remove old pads, reset the pistons, before inserting new pads, and putting wheel back in. I really can’t see how you can do all that in 2 mins.

Why do you need the wheel out, aren't they just like car callipers?

I'll have a try later.

Bet I'm not far off that

You can take them out with the wheel in situ but it can be a little more fiddly. Pushing the pistons back is the main issue with the wheel in place

If you can do that in 2 minutes, you can definitely swap rim pads in 20 seconds

Probably could, yes. My point was that it's nowhere near as complicated or protracted as some are make out.

It really doesn't take much longer. Take wheel out - 30 seconds, most of which is twiddling the through-axle. Take old pads out - 10 seconds, maybe twice that if you have them secured with a screw rather than split pin. Push pistons back, 15 seconds. New pads in, maybe 30 seconds, put wheel back in - another 30 seconds.

That has been my experience, except once when I really struggled to get the screw out - the old 105 callipers used a slot head screw which is rather soft and I wrecked the screw head. Replaced with split pin after that.

I'm sure you can. But it isn't as much harder as people try to make out.

If you can do the job in 2-3 minutes, it really can't be described as a PITA.

Yeah, the brakes "debate" is far too absolutist. There are pros and cons, as I tried to set out above, and not all applications have the same best answer. And of course, some of our is pure personal preference too.

That's a fair assessment. It's the perenial never ending debate.

I'm a big admirer of air brakes for bicycles.

I think you are woefully underestimating how long it takes. Next time you change your rear pads you can film it unedited. Then we can see you match your estimates on film.

I agree, but also the bigger issue is for me that you can't judge whether the pads even need replacing without removing them first. And even then it's not obvious - they're only, what, 3mm to start with?

Whereas for rims a seconds glance suffices.

At least that's my experience. Others may differ.

 

[cyberknight]

Cable discs from my experience are woefully underpowered even when set up perfectly i would struggle to lock the wheels whereas my rim brakes i managed to lock up very easily in the wet

Add 30 minutes looking for the screw that drops on the floor and disappears, 20 minutes for sausage fingers trying to faff with small parts and 3 days waiting for the correct parts to be sent after being sent the wrong uns.
