rotor warping on disc brakes

[cyberknight]

With a single sided caliper you need to be adjusting the static pad inward as it wears to maintain good brake performance. There should be an adjuster on the side of the calliper where you can insert a hex key and adjust the pad. You may have to remove the rear wheel to do that end of the bike which makes it a bit of a trial and error process. Just another piece of poor modern bike design that I love.

Don’t get me started on carbon frames.

yes i know how to adjust my brakes , i check them every time i wash the bike and today i even had to move the whole caliper as it was rubbing one side even on max clearance .Dont even get me started on the front one that has to be reset every time i take the wheel out .👍

I also prefer Suntour Cyclone over Campagnolo Nuevo Record.

Please start on carbon frames. Nothing like a good thread derail to keep everyone happy and gives us the chance to learn.
I confess surprise that, with your implied familiarity with mechanical and hydraulic disc brakes, you keep the tandem rim-braked: for the challenge, I expect, and to keep Frau Fritz thrilled.
It's Nuovo Record btw, well that's the speeling on my RD.

Sorry about the horrid spelling… never my strong point… that and I was too lazy to head out to the garage and read it off the back end of the bike.

Carbon… *sign*… my opinions on the subject are not popular where I currently work (Trek!) but after 30 plus years in the manufacture of automotive components in plastics, mostly bearings and seals, I have some pretty strong opinions on the uses, and over uses, of plastics.

Carbon fibre frames, like fibreglass boats, cannot be recycled in an economically sound or environmentally friendly way. They will live their relatively short lives and then be committed to the garbage heap to become yet another part of the nasty crap with which we are contaminating this world. They should simply be banned as unnecessary and we should learn to live with metal frames and wheels.

There… I’ve kicked the door open… have at it!

Heresy I know…

Obviously barking mad.

Dura Ace 7400 for the win, you peasant

look for some TRP Spyres

I could spend an awful lot of time polishing that stuff… so nice. I saw an NOS top of the line 1980ish Bridgestone roadbike frame for sale last year… they would go together so nicely…

You go 40mph down hill on a tandem?? You are pretty brave!!

been there, done that and stopped it fine with Avid BB7's, which I think we single piston. I recall doing the winding in adj as the pads wore and setting them up with a business card spacer.

mind you the cheap disc brakes it came with were absolutely pants, so upgraded to bigger rotors and BB7s and slung an extra stoker operated V brake on the rear too.

So where do you stand on the carbon disc brake debate?

Don’t you have to get those things stinking hot before they work properly?

I think the very few bicycle offerings work at normal temperatures.

They sound like some the callipers I had to sort out when at the bike recycling centre . I'd get rid and upgrade to something that actually works

doesnt help that the wheels are quick release rather than thru axle

I have TRP Spyres on a QR wheeled bike (and I had the same before on two other bikes), so not sure why that’s an issue?

I saw a tandem ridden by a large couple from Newcastle. The discs were visibly blued from excessive heat.

it was in response to @FishFright , with single piston and qr the rotor never centres the same even when using the brake on the front when reinserting the wheel so if your rotor is warped you need to readjust the brakes so it doesnt rub .
