he's spent the whole day trying to undo
my front bleeding nipples he's tried heat, spanner,
grips, oil & hammer over & over, my nipples are now
pretty round , before we break it & end up having to replace
the whole caliper can anyone offer any advice, please?????

a good pair of mole-grips or stillsons

he can't get any mole grips small enough to get in there..
he's been round b&q & helfrauds & not found anything
of any use that we don't already have, thanks

BnQ should have stillsons , a good 5 ' pair , nice and tight and a good slap should get them nipples turning

could also file a couple of flats onto the nipples to start with give the stillsons something to bite onto

VASELINE + A COTTON SHIRT!

now i almost know how my partner feels when he sees
something on the telly that makes him cringe & hold
himself in a certain way!! ouch!!


thanks, i'll text him cos he's off at b&q again now!

PlusGas ( note = NOT WD40 ) applied a few times for a day or so preceding the work is remarkable effective.

PlusGas

Got a generic version this morning and got both front ones undone after 4 or 5 applications (Still got to find the cause of the binding front brakes, but at least we're working with clean fluid now!)

Cheers everyone

Hi Melvin

I'm havin the same prob with my front nipples.... i wanted to know wher you picked up the plus gas type stuff from? did you use stillsons or mole grips or just a 7mm spanner?

cheers

The binding front brakes will most likley be caused by the pistons in the brakes seizing, as the fluid has not been changed every two years. The new fluid will stop further corrossion, but you need to free up the pistons. Do this by squeezing them in with a g cramp, and then pushing them out with the brake pedal. Do this till the piston moves freely. It will improve things, and might save you having to rebuild the calipers completely.

Seized brake pads are much more common than seized calliper pistons and much easier to put right. Work the pistons back and forth as well.

hi, we got the 'shock & unlock' from helfrauds, it's their own brand of,.
they go out of stock quite quickly though & i had to phone around the localish stores to find some at one point, it's cheaper than plus gas & we found it to be better, less greasy & worked better/faster,.
getting it undone it was the cheap adjustable spanner that did it in the end!
( after filing an edge on both sides of my nips )
i used a special brake pipe (almost complete ring spanner type thing) 14mm spanner that was great for gripping when i removed the caliper, if they do them in a 7mm that would be very useful to you!

we got the calipers off in the end, bought a rebuild kit £12 or £15 sorry can't remeber exactly, took them apart & rebuilt them, was easier than we thought & has cured & improved our problem, one of our problems anyway

hope that's of some help to you

You say brakes binding, both or one side, do the brakes take longer to "bite" and are slow to release after letting the brake pedal up. I know its rare but it could be a collapsed / pinched flexible brake hose (caused by stretching after other work done?), I had this problem with my car a while ago. Easy to prove...if bleeding is harder than normal after renewing calliper parts and fluid, removing or just loosening to allow fluid to flow from the first fixed point union (opposite end connected to calliper) and pushing fluid through that is not restricted its likely that the flexible hose needs replacing. Defo something to check first before calliper overhaul and any other expenseive replacement.

Great thanks, I'll pop down there tomorrow and grab some, i'll call em first

i have just had to buy a new caliper because the nipple wouldnt come out and snapped off. grrrrrrrrrr
