Brake Bleed Nipple Specs - Toms306 - 21-01-2016

Hi guys,

Anyone know the specs for 306 bleed nipples? Looking for rear calipers but fronts may be useful to others.

I didn't realise there were so many with the same size nut. Confused

i think its m7 on the rears

RE: Brake Bleed Nipple Specs - Toms306 - 21-01-2016

Any idea on length? Need that as well as girth, only part I know is the nut is 8mm as I have a proper double ended nipple spanner with 8mm and 10mm ends lol.

Servicebox doesn't list the lengths unfortunately. But they are £6.59 each to buy from the dealer lol! Confused

Yes, really expensive from a dealer.

1.25 ish from big red.

Enquired  about seal kit, not stocked and special order from pug dealer at 28 per side plus vat, they did not know what the kit contained.

Got seals ( 33 deliverd to do both sides ) and nipples from big red, the nipples for the front ( bosch caliper ) being too short, so used the longer ones for the front for now. will post part numbers next visit.

Must get some slightly shorter ones for the front, then correct ones for the rear calipers, bendix.

The front nipple just sheared off, which is what I suspected would happen, but got the remains out using mig blob and bolt method, after stripping down the caliper. The other front one came out intact after heating caliper, once stripped. They are now back on the car and bleed.

The rears are next weeks bag of sweets.

seal kit contains seals and a bit of grease.

RE: Brake Bleed Nipple Specs - Toms306 - 22-01-2016

Servicebox pictures the seal kit, so not sure why they don't know what's in it? Confused

I would have thought you'd know the exact specs, Mei? Big Grin

RE: Brake Bleed Nipple Specs - welshpug - 22-01-2016

m7x1.0 is all I know, I haven't bought any for a long tine but you just need to buy whatever is listed for a bendix or bosch rear caliper

fronts are 7x1.0 or 10x1.0 depending upon which caliper (8 or 11mm spanner)

RE: Brake Bleed Nipple Specs - Eeyore - 22-01-2016

i cant even find the bits i bought for the front ones! TOo many things! D:

RE: Brake Bleed Nipple Specs - zx_volcane - 22-01-2016

m7 for sure on the rear, stupid size thread!

can get ones too long, won't matter as will bottom out and seal regardless

Just measured 1 of my old rear caliper nipples & the nut is 8mm /thread width is 6.92mm (so call it 7mm as its used )& the total length is 26.07mm from the top to the sharp point
Total thread length is 10mm measured from the bottom of the nut to the bottom thread.

I don't currently but I'm sure it could help others. Big Grin

Also, after all that it looks like we have at least one decent one on the calipers Sam found, I have soaked them in WD40 and will have a go at removing them next time I'm over.
