Brake reservoir screw head issue

How do I test for loose screws ? sit on a sofa, neck muscles as loose as possible, look up ... and bang your head from the left or right with your palm ?

Yeah....a 2x4 wooden plank would deliver better and permanent results than palm

You CAN NOT test for a loose screw yourself , someone else will tell you if you have one.....

It's out.

The smaller (3 mm) extractor got stuck in the screw and I was beginning to wonder if I'm going to make it worse. Rotated the 3mm extractor out and moved on to the 4mm extractor. It came out easily. In hindsight, I think the chuck on the drill wasn't tightened enough for the 3mm extractor.


The screw which came out looked ok - but had some of the white powdery stuff in the center.


The new screw did go in easy - so it looks like the threads are good on the reservoir.

Pads replaced. Rode for a short distance and things seem to be good. Now to move on to the speedbleeder installs and bleed the fluids all around - what could go wrong?

for all the suggestions and encouragement.

A story with a good ending.

Nice job Sach, and good pictures too by the way so we all learned something today.
But why one thread is corroded and not the other?
Could be some brake fluid made it's way into the thread previously, easily done when removing the cover and mixed with moisture ( hygroscopic means it attracts moisture ) and started corroding the aluminum housing similar to salt and moisture.
Some grease or gear oil ( spreads out on a surface and wicks in a crevice ) would have reduced this and regular fluid changes would have limited the time corrosion had settled in, even" excersising" the screws a bit would have helped.
Something you have more control over instead of " done by the dealership ".
