cleaning front brake disc bobbins / rivets?

[darrsi]

Well I don't know what qualifications any of these people have (I read that long discussion on the other forum)... 

But anyway the calliper is gonna get a right good cleaning... and the discs - just a non-vigorous toothbrush clean of the rivets and a scrub of the braking surface. 

Give the pad surface a bit of a going over with emery paper, or whatever weapon of choice you have to hand, to take any glazing off them, then after you've cleaned the caliper up i would suggest deliberately putting the pads back on in the wrong order, meaning put the left pad on the right side and the right on the left.
This will upset the natural grain of the pads against the disc and will need a day or two to bed in again, but in the process will clean the discs for you.
If you do have any hotspots on the disc then "giving them a scrub" won't do sod all as they are literally baked on (been there, done that too).
You'd be better off getting the bike up to speed a few times in succession and doing some hard but controlled front braking.


This is another reason why i'm not a fan of softer compound brake pads. It's each to their own, but i prefer a grabbier response when braking, and with less brake dust to cause these types of problems.


Here's a bad example for instance, with some iffy WD40 advice too.

Sorted mine by changing the pads which were down to the metal.  So silly question time Brett,  have you checked your pads by physically removing them?

Avoid soft pads up front, go for sintered.


Been using these for years now, and even though i'm not a hard braker, they just don't wear out, and don't wear the discs either.


Highly recommended.  :thumbup
