My Kenevo SL has recently developed a pretty loud and very annoying squeak which seems to be coming from contact between pads and rotor when climbing or under load and it also seems to be in rhythm with a pedal stroke.
I've re-centred the pads a few times using the tried and tested method but no luck. Visually it all looks perfectly aligned and when in the stand it's silent, but as soon as I'm peddling it sounds like a mouse party back there.
Everything is torqued up properly and it's all clean.
I've had a slight brake rub on previous bikes but it was a faint and completely bearable noise, not a loud squeal like this.
I expect some frame flex given the full squish but I'm wondering could this noise be attributed to the pads specifically? Maybe I didn't take enough time to bed them in?
They're SRAM Code RS callipers and SRAM pads.
Any advice very welcome!!!
Odd that it's in time with the pedal strokes - suggests it's a problem elsewhere (pedal, chain ring, etc.) or something that's flexing when pressure is on the pedal (pivot loose/dirty or worn bearing).
Normally something brake-related is going to be making a noise in time with the wheel's rotation.
Reading the description and hearing it was timed to the pedalling makes me think I'd be checking bearings and pivot hardware first
Less carbs should help.
Same opinion here, wheel/hub bearings and pivot bearings !
Actually, I've just gone through weeks (months) of tracking down a creak on my Nukeproof to eventually find it was the eyelet bearings on the shock. Seems to be a common enough problem on Fox shocks but I'd never heard of it.
If you've got the 30mm bearing kit on your shock, that could squeak too..
Do you run an oval chainring? I traced a pedal timed squeak down to a dry jockey wheel bearing. I think it was the extra pulsing applied by the oval ring that made it squeak
Definitely brake rub. Just took it out for a spin and it turns out the noise wasn't entirely affected by pedalling, more so the pressure applied to the pedals on the left stroke. While coasting I tried leaning it over quite a bit and putting all my weight on the left pedal and there it was... squeak, squeak squeak!
I shifted the callipers in board a couple of mil and the noise was gone.
Definitely going to replace the pads though 🙂
I had a not so loud squeak under similar scenario this week, turned out to be the clutch on my rear mech. Just bobbed some 3in1 through the allen key adjustment hole and it's quiet again.
Loud squeak coming from rear when under load
Remove the gerbil?
