Brake caliper bleed nipples
Hi all
I have to change my flexible brake hoses soon and thought that I'd replace the bleed nipples with stainless. Unfortunately, I can't source as I don't know part numbers/sizes. Are front and back the same? TIA Regards Geoff |
i bought mine from rimmer bros. i had bought alloy nipples from ebay but they were rubbish. they were soft and snapped easily,not from over tightening , but even with a liberal coating of copper slip , would not trust them to not snap off like a carrot after being on some time. the rimmer ones are i believe a little dearer , but have two sizes , same thread but longer on the front callipers. i would go for them,but your choice ... :D over tightening by garages seems a problem most of the time.

I may be totally wrong, but are they different sizes as in 9mm spanner & 7mm spanner?

I can understand your thinking but of course the thread in the caliper will still be prone to rust. The way I deal with the problem is as follows:
I haven't had any trouble since adopting this method for the standard factory nipples. :} Simon |

I like to add a little ceramic brake grease to the nipple threads, i purchased the nipples from a local car store, you can then see what you are getting.

failing a lack of ceramic grease to hand, i have used red rubber grease applied to the threads.it will seal up the top ring area of the threads where exposed to water and gives a good seal. the rubber caps that fit over the nipple are also important to keep out dirt, A lot of folks dont bother with them but they are there for a reason. great photos again Arctic . thanks.

Each to their own - I've always used Copaslip on brake nipples, and don't overtighten them either. ;)
