Pointy SV650 Footpeg/Brake Pedal Bolt keeps getting loose

[SixFiddy]

Tightening said bolt too much disallows the brake pedal from returning upwards and tightening it just enough to allow the brake pedal to move freely results in the bolt working itself loose again (the brake pedal and footpeg move around way too freely).

What's the trick to getting it to stay put?

Thanks in advance :)

Threadlock.

newer pointys rely on the rear brake light switch spring to return the brake lever. to get this to work properly you must keep the brake lever bolt well greased. do not use copper grease, CV (moly) grease is the best but if you dont have that then good old regular bearing grease, if you dont have any of those then chain lube will do as long as you re lube every service by spraying it at the joints of the lever.

the other option is to buy the older (K3) type return spring and fit that.

Tried blue loctite, although I haven't greased it in a while. I'll try that. Thanks for the replies :)

The brake pedal shouldn't bind up up when you fully tighten the foot peg bolt. Is it the original Suzuki brake lever or an after-market part? If the latter then you may need to take a file to the pivot area and slim it down by a small amount to prevent it binding.

Come to think of it, I've only had this problem since replacing the brake lever with an aftermarket/pattern one... I guess it's time to order some files. Makes me think that I should've just bought some CNC rearsets

You could just use some emery paper or maybe even coarse wet and dry paper on a flat, hard surface. It's an alloy lever so not hard to remove material. At a pinch you could probably even scrape it with e.g. a stanely blade.

Just make sure you clean out the bushing afterwards and re-grease.

Had the exact same problem myself a week ago when replacing rear brake pedal. Solved it by tightening the bolt to correct torque and then loosened the brake light adjuster situated behind the foot rest bracket. https://uploads.tapatalk-cdn.com/20180423/f625b82271c6388528f360a132d35c82.jpg

If your brake light switch was screwed down so far that it prevented the pedal returning fully, then loosening or tightening the pivot bolt wouldn't help.

I think that’s the point I was hoping to get across but probably didn’t go into enough detail! I didn’t want the OP getting sidetracked by types of thread grease and brake levers - which are still useful and relevant - because it wasn’t the bolts that were the problem. I realised after tightening the footrest pivot bolts that the brake light switch adjuster was too tight and was not allowing the pedal to return fully. Loosening it solved the problem completely while still leaving the bolts tightened to the correct torque.

That's quite interesting actually. Did you happen to replace it with a pattern part from eBay too? If so then it's likely that it's just an issue with having to adjust the brake light switch adjuster if using said part :)

No I was just replacing a broken brake pedal and had the same problem as you when putting everything back together. No other parts were replaced, I just didn’t realise that the adjuster was too tight as I hadn’t done anything to it, so I didn’t notice that it was the problem! Loosened the adjuster until the brake pedal was able to return to it’s normal position and the brake light went off as it should.

Sorry SixFiddy, didn’t read my original post properly (drinking and posting don’t mix!) In answer to your question - yes, I fitted a new OEM brake pedal from eBay but it was not part of the problem. It was the adjuster that solved it.

Hmm I'm trying to get my head around why the adjuster messes things up despite not being touched

Just an update, this didn't work for me. It's definitely an issue with the pedal itself so I'm going to buy some files and try one of the other suggested methods :)

Update #2: Fixed the issue using mikerj's suggestion of filing down the pivot area. Worked like a charm. Thank you!
