4211-046 Barrel & stud assembly
Front brake master cylinder barrel and stud assembly, later superseded by 99-7027S.
99-7027 is a barrel and stud assembly for the front brake master cylinder, the part that houses the piston bore and mounts the cylinder to the handlebar clamp. Our catalog shows it in front brake figures spanning 1979 to 1983 appearances, so it's a part that stuck around through several seasons of production.

This is the barrel itself along with its mounting studs, not a full master cylinder kit with all the internal seals and piston hardware unless stated otherwise on the listing you're ordering from. If you're rebuilding a front brake and the old barrel is pitted or scored inside, this is the piece you replace rather than trying to hone out corrosion that's gone too deep.
Our records show this number was later superseded by 99-7027S, so if your parts book or an older order references 99-7027 and you're having trouble finding stock, that newer number is the one to search under. Confirm which master cylinder body your bike takes before ordering, since front brake hardware changed across these years and we want to get you the right one the first time.
