Hi, thank you for watching and for your feedback. The video is primarily to show as a guide to disc / rotor replacement, the inspections / renewing or cleaning of any relevant items has to be left to the discretion / experience of the person carrying out the repairs / replacements as this cannot be achieved remotely. Yes Jaguar do say " discard the old bolts " but if you read the full general advise " various thread-locking devices are used on nuts and bolts throughout the vehicle. These devices restrict the number of times a nut or bolt can be used ". The advice is not that the standard nut or bolt ( not including what are commonly referred to as stretch bolts etc ) is defective but the thread-locking device is, now if this thread-locking device is incorporated into the nut or bolt and is restricted to the number of times it can be used then at some point it will need replacing, on the other hand a thread-lock that is applied externally to a nut or bolt, ( serrated washer / spring washer / tab washer / lock-tight etc ) can be replaced without replacing the nut or bolt. Spare parts sold by the manufacturer yield high profits.
Thanks for the feedback / reply, Yes you are correct, we inadvertently edited that explanation out of the video. The placement washers are available from jaguar at £2.70 each ( 2 per hub ), we took the video on a Sunday and as seen the washers were not replaced by whoever did a previous disc / rotor replacement. It is not a safety issue as the wheel holds the disc / rotor in place when driving, not the washers. Again thank you for your feedback as it has alerted us and allowed us to post this clarification.
I bought a set of new discs (Pagid) which I hope to install this Summer. The discs are coated wth a coating (paint?) which keeps the working surfaces free of rust until installation. Is it advisable to remove this coating before installation, or will it wear off by the pads during use? Will this coating contaminate the pads? I ask because your discs seem to have the same coating. Nice series of videos! Find the subjects on the XK (X150) useful.
Hi, thank you for watching, the discs have a polymer coating ( NOT to be removed ) which is designed to prevent rust for as long as possible when fitted. It is designed for brake pad wear only, leaving the remainder of the disc coated. The coating will not contaminate the pads. When removing and fitting the discs they do have 2 spring washers ( not shown in video ) which hold the discs in place for ease of assembly ( not a safety issue ) sometimes they are on the studs and other times not. can be obtained from the Jaguar main agents if needed. Many thanks again for watching and for the feedback.
Hi, thank you for watching and for your feedback. I will as you have asked, film a video of the rear brake disc / rotor and brake pad replacement soon. Thanks again for watching.
Thanks for your feedback / reply, the video is primerily to show disc / rotor replacement. Brake pad removal / inspection will be covered in another video. The assumption that new pads "need" to be fitted when new discs / rotors are fitted is false ( most likely originating from free brake check fitters to generate more income ). If original brake pads are free from any defects / are wearing fairly evenly ( across the set of pads } and have adequate wear left in them then there is no need for replacement. Thanks again for your feedback as it has allowed us to clarify this.
@@crystalclearmechanics However the pads will have the exact profile of the old disks so will not be perfectly flat like the new disk. They will wear in but they will also prematurly wear the new disk. For the sake of a small cost it is definitely advisable to fit new pads with new disks. I take your point about demonstrating the disk replacement though.
@@stevenjarratt2454 Hi Steven, thank you for watching and for your feedback. I understand your point but you are assuming the pads have defects. Even a small cost ( not always viewed by everyone ) is a waste if unnecessary. Just as a matter of interest do you renew your discs each and every time you renew your pads? Thanks again for watching.
5:20 - Just as an added tip, if you put the bottom bolt in first, it's just as easy to get the top bolt in. Sorry, being a dick. But still relevant and factually correct.
