Calliper Bolts On A Zx

[S00TY]

Hi I have just come across this forum so I'm hoping someone with more brains than me will be able to help..

 

I inherited a zx 1.9 diesel witch I use to get to and from work but a couple fo weeks ago noticed that the front n/s wheel was screaming so later on i had a look and found that both pads and disks needed changing which i duely did. Now this is where it starts to go down hill a little, once it was all put back together i went for a little test drive and all was well but the next time i used it for work which is about 10 miles away the n/s brake was hanging on and the wheel was hot and stunk of burning pads. Now my question is the 2 bolts that keep the calliper on which allow the calliper to slide do they need to be very tight or do you slacken them enough to allow the calliper to move freely but keep them tight with something like lok tight.

 

Hope someone can help as it's starting to drive me nuts!! :rolleyes:

Yes They need to be torqued up quite tightly. Forget to what just now but 70-80 lb/ft won't be far away. If the calipers are sticky, take the slides out and clean them up. put them back together with fresh grease (High melting point) taking care not to damage the little boots that keep out the crud. Make sure that the new pads can move in the housing and the parts where they rest on the housing should also be lightly coated with Copaslip (Copper Grease) taking care not to get any on the disc or friction surface of the pad. Hope this helps. Cheers

yes ,i agreed with colin. do it on both side so that i will have the same 'clamping' movement.

Right, Ive managed to get my brakes up and running now i.e relasing fully and not sticking on and overheating and I was hoping that that was over and done with, However tonight I have just had 2 new front tyres fitted and noticed when the tyre fitter removed the o/s wheel both the little spring clips that sit under the t peice of the pads had gone which can then allow the pads to move arround a little.

 

Now my question is, is there some secret way of putting these clips on as I thought I had put them on rightby jamming them in between the pad t peice and the calliper slide but i guess not as they seem to have dissapered!! What I need is to see a picture of how to put the springs in place so if any one has one lieing arround and is good at uploading then please show me before I start to hate my zx :rolleyes: :angry:

 

Hope some one can help

OK! Don't have a drawing handy but basically where you have gone wrong is by putting the wrong part of the spring under the horn on the pad. There should have been a fitting guide in the box along with the pads which should have told you how to fit them. But if not, Here goes. If you have lost the springs, replacements are available. I got a kit from Citroen which had the springs (4) the retaining slides (2) and 4 of the little clips which secure it for £14. Right! just had a search on the web and found this document. http://www9.qha.com/uk/technical/downloads...partnership.pdf It's a Quinton Hazell Technical bulletin so it's kosher. There's a bit in it about fitting your brake pads (Page 10 I think). Unfortunately it does not mention the springs. So! One end has a rectangular section which fits over the horn at the forward end of the pad. You will notice this has a slight "Crank" to it The other end clips over the centre of the pad. Fit the rectangular end so that the inner end (nearest the centre of the pad) goes under the "Horn " the cranked end sticks out past the end of the pad and lies against the surface of the caliper. You will know if its right as you should be able to press it down against the spring and it will rebound (Very small amount of movement) When you have both pads in place, slide the "L" shaped retainer into the other end of the caliper and secure with the small clip. Cheers Hope this helps.
