Brake Nipple removal ?

Post by IanD » Thu Jun 15, 2017 10:52 pm

Can anyone recommend someone to remove siezed brake nipples ?
Ideally Glasgow area or central belt or somewhere that does it via post ?

Don't want to risk calipers being damaged.

Would be worth trying Ken Brown in Hillington.

if your talking front caliper (ali 2 pot) heat is your friend.

empty out all the fluid, remove pistons and seals, then heat the crap out the housing around the bleed nipple.

ali expands ~3 times the rate of steel, so the hotter it get's the looser the grip on the nipple.

once you have it hot, tap the nipple, (not with a club hammer!) then try and rotate it.

Youll also probably find the threads will gall up when removed and you will need to make an insert.

Cheers, I'll phone Kenny Brown and see what they say.
I'm not best at car DIY so looking for someone to sort them !
Had a problem with a rear caliper while in for service last year, the last (Porsche) indie sent them off somewhere to be sorted without telling me cost me £55 in postage + £70 to fix them wasn't best pleased at cost esp. the postage charge.

Find someone with an inductive coil gun, heating the nipple should be sufficient to break free any corrosion and no need to strip the pistons out.
