Front brake reservoir screwed!

[Evilchicken0]

which model is this for ? The clip-ons are below the fork yokes so it's 1988 or older.
I'm asking because you say the callipers are suck as well, it might be better to get a system with the callipers as well but the callipers can differ .... are they four pot (100mm bolt spacing) or two pot (83mm bolt spacing) ???

The brakes were sticking a bit when I got the bike, had been sat for 18 months untouched. I had the callipers off and used a clamp to push the pistons back.

You cleaned the pistons first so you haven't pushed the crap back under the seals ... ?
Yes that will fit

I gave them all a good spray with brake cleaner spray and a wipe over, should I have completely removed them from the calliper and polished them up do you think?

Even though it's for a Fazer? Forgive my ignorance!

[Evilchicken0]

Yep - even though it's from a Fazer.
If you don't want to take the pistons out then use the master cylinder to pump them out a bit first, then clean them then push them back. A light smear of red rubber grease helps. I'm guessing you have the two piston calipers (one each side of the disk), when you wash the bike hose them down, it helps to keep them clean.

It will be more cost efficient to repair the original caliper either by removing the damaged screw, helicoiling back to original size or tapping to the next size up if you had the skills/gear or a cheap garage contact.

If you get new stainless screws for the master cylinder use a copper grease on them.
Do not be tempted to buy the allen key type....the key size is far to small for the application and will round out after a few uses. Buy this type ;

They are all the same length and thread.

The original "coffin" master cylinder should not be expensive to replace if you wished to go that route....I have thrown
probably 6/7 away when uprating brakes.

The problem with buying used master cylinders from breakers is ; they have lain ,usually bone dry on a shelf for months at least. The seals dry out and when fitted and bleeding is attempted, the piston and seals travel further than they have when in use and the seals often fail.You then have to buy new seals adding to the cost. (In my experience in about 40% of purchases.)
You also need to do a little research as to which calipers the master cylinder is designed to operate.
If you use the master cylinder from a bike that has blue spot calipers on your 3EN1 with its original calipers then the brake lever will not have the "feel" that it had originally as the ratio is different. The fact that a span adjustable lever is fitted is a good upgrade though. I seem to recall that the lever will nearly come back to the bar even with new braided hoses and fully pressure bled.

Here is the Fazer master on a 3EN2 but fitted to the blue spot calipers.

That's why I asked about the model and callipers

Cheers for all the help and advice, have been given a quote of £20 by a mechanic up the road to helicoil the existing one so will remove the reservoir and take it to him tomorrow hopefully.
