Squeally drum brake

[talkToTheHat]

The drum brake on the rear of my 535 has started squealing during slow ride conditions. It's fine fully off or if I use the brake hard, but just a touch makes all the brake squeal imaginable. Is this within normal operating parameters or do I need to get it looked at.

I had the brake shoes changed for EBCs last time I had tyres done, between 2k and 3k ago.

Is there any play (or even a bit of fresh brake friendly ((graphite?)) lubricant) in the brake cam lever?

[Copycat73]

when we bought her xv535 the back brake would grab very harshly or squeal at speed.... basically it was full of crud.. mostly rust but also some brake dust...
#
I removed the wheel wit the brake assembly..
Emery clothed the inside of the brake drum and the surface of the shoes to remove any glaze...
Then poured boilin water and a little squeezy and scrubbed wit a new toilet brush ...
The pivot actuator needed a greesin aswell..you can check this for play at this point ..
re-assembled and problem sorted..

tl.dr. non expensive job but takes time and some skill.

It's quiet at speed, it's not grabby, it's just when I'm only just applying the rear brake it bursts into song.

No, I don't think there's any lube on the cam.

Tempted to investigate this myself.

Copycat, how did you lift he 535 to get access to the rear wheel?

me thinks you should get a manual, and see the exploded views on cmnsl which may help you...........or take it back to the garage and pay them to do it......brakes are safety critical and your not sure how to take the back wheel out, so........

When I said cam, I really meant cam lever. My bad. Specifically the portion that passes through the backplate. But yeah, dedusting as said, would be good.

[Islander]

Before you get too deeply involved in complcated solutions, try removing the wheel and cleaning the dust out of the drum.

.......and then rough up the shoes with some course glass paper

I've had the back wheel out before. I know how it comes out. What I don't have right now is access to useful things like a proper bike table, which with some wooden props under the engine and some ratchet straps will lift a 535 quite stabily. Then it's undo the torque arm and brake linkage, undo the pinch bolt, then the spindle nut, the spindle comes out, catch the spacer before it gets lost, and the wheel comes out. Simples.

The problem boils down to the bike is a bastard to lift and I won't do that on my own so before I fuck about calling in favours to lift it, or pay a shop to fiddle with it, I might as well work out whether a bit of squeal is a problem.

Ok. I am pissed again.

OT. Ask advice, get advice, and then baww? Am i following the topic? Do it, get a shop to do it, or live with it.

Anyroadup.

Scissor jack will help you prop it up. You can use this jack forever, they are cool.
Admittedly, these are git bikes to deal with the rear end; pull the shocks- back end will drop enough to pull spindle/wheel.
Undust. Clever people said 'do this'. Dumb cunts like me only jump in to state the fucking obvious!
Clean with brake cleaner, small smear of grease on the lever as it passes through the backplate. Check, clean and lubricate the system back to the pedal.
Whilst your hands are a bit manky; tug, pull, rattle and shake other shit on your bike. Tighten, replace, repair or moan as neccessary.

I'll get it looked at.

Major Dross, calm down, I'm not bawwing at you.

Lifting the 535 is a ccomplete batch as most cheap portable solutions don't work. pit stands, abba stands, small scissor jacks and cruiser jacks that rely on frame members underneath the engine do not work well.

That I know this is a major issue and I need to make arrangements for assistance does not mean I do not know how to disassemble a braking system. I'm quite happy doing drum brakes on cars. For that I need a trolley jack and some axle stands, which are far easier procured.

Yes I need to sort my life out and get a bike that is less of a batch, or secure an area for work and tool storage. I'm working on that.

Clean it out thoroughly with meths, including the shoes, it's amazing how much seemingly non-existent crap that stuff can shift.

That could be just the thing. I might know someone who's got one. Will consider getting my own once the living/working area is sorted.

[pompousporcup...]

where are you based? I have a folding crane good for 2 tons you could borrow if needed..and aren't too far

[talkToTheHat]

Doncaster or thereabouts. Guessing by the yellow dot on your profike that makes me a bit far away. But thanks for the offer.

Was checked at the garage yesterday as the bike was in for fork seals. Apparently EBC pads make all the dust in the world. Greased carefully and reassembled. Quiet now.

Apparently there was nothing to worry about other than the embarrassment factor of having breaks louder than my exhaust, and having a drum brake.
