Brake calipers ATE or Girling? and bleed nipple thread size?

Hi

I have been looking at getting a brake caliper seal kit for the van, one caliper is sticking, I dont know what caliper I have ATE or Girling its the same as this type



I expect the bleed nipples will snap so I will order some new but what size thread are these too?

Thanks

 

M7x1 for the nipples

As for make... it is normally cast into them, unless they are very rusty!!

 

Forget about refurbing it - spend £65 and get a replacement .....
Snapped bleed nipples are par for the course and can be a barsteward to remove .

I`ll say it again for the hard of hearing ....
FORGET ABOUT REFURBING IT - SPEND £65 AND GET A REPLACEMENT ...

 

If you are set on a refurb mate and are anxious re getting that nipple out i suggest you visit local comm. garage,find oldest mechanic there ,show/explain situation appeal to his many years experience whilst waving a £5 and (well from my own experience)he will no doubt rise to the challenge .>>combination of Looseoil wire brush ,heat and time , lots of time ,and he will know the size ,best wishes.

 

I believe Girlings had the fluid pipe connection right in the centre of the calliper face.

 

The bleed nipples begin life as 7mm but will rust down to 6.35 mm so the wrong end of the brake spanner works... And you might get lucky and they come out without shearing off using mole grips and carefully applying torque. "Worked for me"

 

Mine were way rustler than that! Blowtorch and mole grips. Job done

 

.

 

sometimes if ones sheared and someones drilled it out you may have a bigger one?

 

Thanks here is another photo, i don't mind having a go at refurbing them for £20 for the seal kit it's worth a go

 

Need to see where the solid brake pipe enters the caliper.

 

I don't know if it is the where the brake pipe enters - my old calipers had ATE stamped on them and came out of the centre, but my new calipers had the brake pipe coming out from the top ...but was also stamped ATE.

You can tell the difference from the retaining springs and backing pads:

By the looks of it you have ATE

 

Quick update took the other wheel off and I can see ATE 11 14 stamped in it and the brake line goes to the center .

Thanks all

 

Assume you split the caliper to whack the piston? I use a cheap piston compressing tool like this one.

 

So after you whacked and freed it I assume you didn't take it right out because I can't see how you could have? If they sieze it's rust which needs removing. If you don't remove the rust they'll seize again in no time.

 

I freed mine off by making a thick wooden brake pad and fitting it into the unsiezed side and then just used the brake pedal to push the other one out nearly all the way.
