Front disc brake bolts

[keno]

Are the front disc brake bolts the same size as the rear disc bolts for a 98 fazer?

cheers.

According to the AJ Sutton site they are the same part number,so yes they are.

Apart from the rear ones are horrible bastards to undo.  :'(

Trust me, the front are a walk in the park in comparison, they weld themselves onto the rear wheel because the rear disc is not floating so it's a direct heat transfer.

Are the bolts t45 as that was what i used to undo the bolts,need to be sure before i put new bolts on and chew them up.

Can't answer if they are the same front and rear but when you do put bolts back in remember to give the thread a splodge of copper slip that way if you need to take them out again at a later date they won't be as difficult to undo. You probably already know that but thought I'd mention it just in case  :thumbup

Gotta be careful with Copper Grease as it alters torque settings, and disc bolts should really all be torqued correctly.

so torx or allen
They will be going on with a dab of thread lock and coming back off if ever with a blowtorch

Only if you use way too much, I'm only talking about a thin rubbing around the thread

"Technically" it shouldn't be used at all with brake discs, as they're one part you don't want breaking loose.
I can't find the exact post on here that i sent before, but it explained how dodgy the stuff is to use if used with a torque wrench.
After a bit of a ponder, it does make complete sense that you're lubing a bolt with an anti grip lubricant to avoid future shite, but it makes it more susceptible to over tightening by accident, or by seeing a false reading on a torque wrench.
I learned all this when i shredded my rear caliper bolt doing the 'right thing' at 10 or 12Nm using Copper Grease.  :'(


Yet oddly enough, if you use engine oil, not only does it lube nuts and bolts in a similar way, but torque settings can be used in total confidence in comparison.


Because i work with very sensitive equipment on a daily basis, i know "right from wrong" so now nip things up by hand, but certain things on the bike, like discs, or header bolts, for example, should be done properly.

Found it, very interesting read....

Got me discs on and stripped calipers and replaced seals just wondered if it is worth putting red rubber grease on the seals?

Yep, that's what it's for and won't hurt at all in moderation.

+1 for red rubber grease, Just make sure you wipe off the excess afterwards so grit doesn't stick & collect around your piston.

[keno]

Will use that then cheers

Why not around the pistons? It stops them from rusting and prevents grit and dirt getting near the seals. Although it may seem like there's a ropey looking collection of dirt it'll only be on top of the grease, and not going any further.
When it comes to cleaning them again next time it will all nicely just fall straight off with brake cleaner spray and a slight scrub of a toothbrush, ready to be freshly greased up again with the minimum of fuss.
As the pads wear down the pistons will only be going outwards rather than inwards anyway as well.
