Brake pad depth/thickness?

[yorkie_chris]

If you are using up whole travel braking on smooth tarmac you need stiffer springs or more oil.

It could well be that you are getting chatter because you have no travel left... But I would expect that to happen at point of hardest braking not as you are easing off the brakes.

I think the pre load is set relatively soft at the moment... would increasing pre load not improve it?

Thanks again by the way, I am a retard trying to understand this.

DW I asked way more dumb sh*t than this in my time... I still do

Increasing preload will raise your ride height in any condition. What is your static sag at?

Is that the chrome showing with me on the bike or off the bike :S

Edit google says without rider... just measured it at 115mm of chrome showing.

Edit 2... 115mm is the bike just sat flat on the floor with no rider... I just read somewhere static sag is lifting the front off the ground. I'm not going to be able to do that

There is so many different topics with people suffering the same when you google the problem... none of the started topics ever find a solution though lol

This is another one mentioning the bobbins on the floating discs... I cleaned them up tonight quite well some were really tight so will try it again tomorrow if I get a chance to see if its made a difference. This would make quite a lot of sense as the brake will be at their hottest after hard braking.

Will also up the compression damping so its cable tie finishes slighly higher up.

Bear in mind with comp that you have 2 springs and a force*... comp is damping and cannot support the bike, it can only slow the movement.

With heat my theory is the disc is taking a temporary warp because of lack of clearance.

lack of clearance due to the bobbin things getting clogged with dust/dirt? Because they are dirty the disc is getting hot during hard braking, expanding but having nowhere to move so temporarily warping?

Only getting truely hot when braking hard to a stop due to lack of air movement around the disc at sub 10mph

The cleaning has not worked.

I have just increased my preload twice and the virbrations seem much less, at one point I locked the front end up for a few metres (yes **** myself) interestingly the cable ties still finish about 21mm mark.

Right I just wound the preload back to completely soft.

Default is 5 turns clockwise.

I was running at 7 turns clockwise and getting vibration.

Then I increased in stages until 10 turns clockwise and vibration were much less, struggled to replicate it with locking front up.

The preload has another 5 1/2 turns available. 15 1/2 turns in total.

The cable tie is still finishing at about the 21mm mark, should I just keep increasing pre load until that increases? Does increased preload mean the front locks up easier under hard braking?

I've just changed my rear pads this afternoon and thought I'd post a couple of pic's

New pad showing 5 mm of thickness


Old pad with 1.6 mm left on it.
