'All of your four nipples will be the same ( he said to the alien in the star wars canteen). I bought them as a pack from Citroen. There's also a fifth one in there for the brake security valve aka doseur which didn't actually work on mine as it wasn't pointy (tech speak) enough and wouldn't seal.

pretty sure front and rears are different, i thought they where the same until i had to buy new ones for the rear as my stock of front nipples won't fit in the rear.

[Mickey taker]

dont forget I dont have A.B.S , I dont know if that makes a difference

[MULLEY]

They are different as per Vanny, no difference between ABS & non-abs calipers.

Rear ones are M8x1.25, not sure about the front ones...

[toddao]

The doseur bleed is also 8x 1.25

As I said, I bought a pack of bleed screws from Citroen - five the same and fitted them all. So something's not right here. I just looked on Service Citroen but it doesn't specify the gauge of the front bleed screws. If I get a chance I'll go and measure down the barn. The rear bleeds are still available from Citroen whereas the fronts are not which does seem to suggest they are different..

I've got to bleed the brakes on the silver one tonight so will measure the thread size on the front and report back, if you don't get a chance Todd. I'm certain it's larger than M8 though.

[smiffy1071]

somehow, I don't think it is... just see if a hydraulic pipe joiner will screw in...

service citroen dont list a kit with a nipples in,

all three nipples have different part No's though,

saucy devils!

I only wanted to buy the doseur bleed and all they could supply was the five-in-a-bag...... nipples

I wonder if it's the length rather than the diameter which is different - if that's the case there would be a certain amount of interchangeability

[mat_fenwick]

I took a front nipple out and measured it this evening. It was a bit of a rush job, as I'd just dragged Lana out into the rain to help with bleeding when I remembered I needed to measure one. So as she was sat around grumbling about the TV she was missing I took the nipple out - 8mm thread and I measured 10 threads at 9mm. That would give a pitch of 1.1mm(!), so I suspect I miscounted, and actually measured 11 threads. That would give a size of M8 x 1.25.

I wonder whether there are some reconditioned calipers out there with larger nipples, if the exchange ones had damaged threads. I've certainly needed different spanners for different front calipers, although that's no definite indication of thread size.

[citsncycles]

Quite possible - or there could be aftermarket ones out there with different size nipples because they've standardised across their range
