A little advice please gents and ladys,

On removing my rear calipers the other day i made a massive school boy error and cracked off two and removed one of these bolts, before i realised they where the wrong ones. In the attached file taken from the online manual it says not the lossen or remove these. have a i made a big boo boo?????

If your changing the disc's you have no choice, as far as i'm aware, but to remove these olts to take off the calipers, also makes it easy changing the pads?!?!

 

i just did a full set of disc and pad change and i took off the bolts to remove the calipers, just make sure that you torque it to the right amount, cant remember off the top of my head what it is. sorry, must be in the online manual somewhere.

 

HTH

sorry maybe i wasn't clear enough. i've removed the calipers removing the correct bolts(as i'm changing my brake pipes and a few ball joints), but before that i removed the two that are circle red in the picture at the top of the thread. As is says not to remove them i was wondering whether i f00ked the calipers or not.

The bolts you broke hold the two halves of the caliper together. They will need replacing or they will split apart when brake hydraulic pressure is applied. Don't split them. It may be better to either take it to a decent engineering shop or get another caliper from someone who is breaking a car up.

Sorry, must have been the way i read the post, my fault!

As long as the two halves of the caliper have not moved then I'd put the two bolts back in and torque them up again. Test the brakes and check very carefully all round for leaks, if there are none then you should be ok. This isn't rocket science, it's two bolts holding two pieces of casting together. I reckon if you undid the bolts and tried to split the two castings by hand you'd have a job to do so, especially as they will have been in place for about 15 years or more.

 

I did exactly the same to one of my Citroen calipers once, this one actually fell apart so I cleaned up the two mating faces, put a smear of hardening gasket compound on them, bolted them up again and it's been fine ever since. Admitedly, the Citroen caliper is a little more (ahem) 'basic' than the Nissan one, but the principle is the same.

cheers guys, the calipers didn't fall apart and when i get them back on a through check is in order.
