Front brake reservoir

[OAPJinx]

Hi All

I have a 2011 mk2 abs and one of the  screws on the front reservoir had rounded off so needs removing. I am planning to try screw extractor but think may have to drill it out so anyone know if the mk1 abs has same reservoir in case need to replace it?

 Hello. If you check out Fowlers website, it looks like it’s the same part number for both bikes. Double check yourself to make sure.

 Which screw has rounded off?

 If it’s one of the lid screws, I think they are to small for a screw extractor.
 They are countersunk headed screws. Carefully drill off the head of the damaged screw. Remove   the other for comparison. Do not get any swarf in the reservoir. Remove the lid. With the head drilled off screw you should now have a short stub left that is screwed into the casting. Use pliers/mole grips to remove it. Good luck.  New screws available quite cheap on e bay.

You're overthinking this. That screw is just nipped up, assuming monkey boy hasn't been at it shouldn't be tightened to any more than 1 or 2 Nm at most, although if the screw or thread has been in contact with brake fluid there might be some corrosion causing the threads or head to seize but even if it is seized or over tightened you should be able to remove it with the correct sized screwdriver (No2 JIS or Phillips) assuming the screwdriver point is serviceable. Failing that try a No1 or No3 JIS or Phillips be careful not to damage the screw head any more than it already is, all you should need is a minimum of purchase to get the screw turning (lefty loosey remember). If it still refuses to turn a careful tap or three with a sharp centre punch or small cold chisel on the outer part of the cross point or screw head will get it moving.

Obviously replace the screw, its a black zinc M4 x 12mm countersunk head machine screw.

Top tips - Regularly check and replace any of your cross point screwdrivers where the driving points have become worn or damaged. Research torque settings for various sized nuts, bolts and machine screws, many fastenings only need a nip to be secure.

 Totally agree Art, I perhaps wrongly assumed that OAPjinx had already had a go that way, and that’s why he had mentioned a screw extractor.

Screw well and truly rounded off by previous owner I should point out.

Head snapped off and sadly nothing to grab hold of. Was able to cover the reservoir so drilled it out and have some replacements screws on order.

Had tried all the above methods to remove screw as fortunately not my first rodeo but appreciate the response

Good to know that it appears as if part is the same if I need to replace

Cheers
