RE: brake calipers - Rusty2009 - 19:th-Aug-2015 I tried that made it worse. RE: brake calipers - tucpal - 19:th-Aug-2015 Is the rubber sleeve ok on the bottom pin RE: brake calipers - Rusty2009 - 20:th-Aug-2015 Yes mate, I think the problem is like what you said before once the pads get half worn. RE: brake calipers - tucpal - 20:th-Aug-2015 Sure the play in the caliper gets worse with wear I have changed 2 sets now at the half way point and this cured the problem every time the wear is always even but noise starts at the half way mark strange RE: brake calipers - Rusty2009 - 20:th-Aug-2015 I think it could be the pads not sliding back when the brake is released, so using that Bendix to glue/bond them to the calliper resloves the issue. It drys like a silicone rubber and easy to remove so I've been told. RE: brake calipers - tucpal - 20:th-Aug-2015 i will try it next time a service the pads but there brand new at the moment so next summer i will give it a go RE: brake calipers - Paul A - 10:th-Oct-2015 I have a 63 plate J series, so it is what 21months old. I had new front discs fitted July 2015 - due to bad vibration under heavy braking. I now experience a rattle cum knocking from the front disc pads in their carriers. My garage says the pads are very slack, particularly the inner pads on both front wheels. Packed with grease the noise goes but as soon as the grease wears away they start to rattle again - sounds as if there is a serious problem with the front wheels. I am assured the problem is the brake pads being slack in their carriers. Garage have placed on order new brake pad carriers - will this resolve the problem? Annoyed to find that Vauxhall have two qualities in replacement part - after service parts and better top quality parts! Never had this problem of brake pad rattle pre the brake discs being replaced! Is it because of the cheaper version brake discs being fitted??? brake calipers - Rusty2009 - 11:th-Oct-2015 Could the metal shims be missing? I've not heard of anyone else with this problem.

The garage says the pads can be moved by hand when dry fitted but when packed with grease there is no movement. Really does sound like a bag of spanners rattling when driving over anything other than a very smooth road surface. RE: brake calipers - tucpal - 13:th-Oct-2015 Ok what may have happened is there is one rubber sleeve on the bottom brake calliper pin this may have split or be missing or even worn your best bet is to order new brake caliper slider pins this should sort the problem out your brakes should not be that noisy this will most likely be the issue they can perish very quickly if the wrong grease has been used cooper grease is a big no no on the Astra j slider pins RE: brake calipers - Paul A - 15:th-Oct-2015 The car is in again on Monday at a Vauxhall garage. See what comes of that and will let you know. Thanks for the help so far, appreciated! RE: brake calipers - tucpal - 15:th-Oct-2015 Your welcome hope you get it sorted RE: brake calipers - Farrael - 23:rd-Aug-2016 Hi! I've the same problem... When I'm driving on a uneven surface I hear a rattle and when I put my feet on brake pedal the noise dissapears. A year ago I left the car at the garage and I know they put a grease on the pads but a month ago the rattle started again. I'll try to ask them to check the caliper pins or the pad clips.
