likewise what does mean !
Oh dear, the youth of today, just what are we to do with them? Now pay attention class!
All modern cars have sealed components, for example balljoints etc. So when the rubber seal lets go all the grease runs out, the moving parts run dry and wear out rapidly. Then you replace the whole item for £££s. But old cars used to have grease nipples fitted on most moving parts like suspension items, and every service you attached a grease gun and refilled any lost grease, or even forced through enough to completely change the grease inside (the old bring forced out the other end).
This meant often components would last for years and you never had problems with squeaks. Now if someone has started to manufacture Alfa suspension components with grease points this means that owners will be able to keep them lubricated ,and they won't squeak plus they will last a lot longer.
Bleed nipples work on the same idea except the other way round - rather than pushing fresh fluid or grease in, they are for drawing it out, usually to change the fluid and remove any sir bubbles. So Alfa owners will bleed thier hydrolic clutch systems for example.
The last car I know of to still have grease nipples was the Metro!
