andlid Posted March 16, 2009 Share Posted March 16, 2009 Hey, How do I check if my wheel bearings are gone on my right front wheel? Thought it was a stone or something stuck between the pads and the rotor after a handwash (never going back there again) started squeeking a bit when I was driving away from the wash. Was driving it a bit and then tried to drive it off (don't think that was a good idea) after that failing I took the wheel off and had a look at the rotor and bads, cleaned it with brake cleaner spray and tried moving the disc back and forward, no proble in doing so. Fitted the wheel and off I went, all sounded well no squeek! After about 5 min of driving it started again, when I then turn right and left *jugging* it goes then just to start again Thought it was due to this 'thing' being stuck there but it's starting to worry me and I'd like to know how to get it checked by myself before I run and order two new bearings from the shop. Any help would be appriciated... Quote Link to comment Share on other sites More sharing options...
AUTO EXPRESS Posted March 17, 2009 Share Posted March 17, 2009 spin the wheel by hand to check for bearing noises, and also get hold of the wheel top and bottom and push and pull on wheel for any movement or play in bearing. Quote Link to comment Share on other sites More sharing options...

stanski Posted March 18, 2009 Share Posted March 18, 2009 i guess the zed has sealed for life bearings and tjey should be quite tough and last at least 60k even if you drive like a muppet on corners all the time ? I had similar noises could''nt see anything but they have stopped now. Most probably brake related? how much meat on your pads? what mileage is the zed and when they washed the car was a pressure washer directed at the wheels? Probably dislodged some crap into the brake caliper? does itt do it when you reverse? Quote Link to comment Share on other sites More sharing options...

Probably dislodged some crap into the brake caliper? does itt do it when you reverse? = drive like a muppet some times... They are sealed allright mine has gone 53k (km) so far away from 60k I'd wish it's brake related might take the caliper off this evening to have a look, not sure re the meat on the pads hope they're not gone (would have thought it would still make noise even though I'm braking but when I brake the metal noise goes away) I'd say the blind fecker that washed the wheels just stod there with a pressure washer on the wheel... It does do it in reverse (once) when I had it sounding like that before I parked the car. Thanks for the replies, the bloody thing is 390+IRISH VAT each + labour Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted March 18, 2009 Share Posted March 18, 2009 my guess is a siezing caliper, fine on a cold start, as it warms up it starts to bind, doesn't retract properly after a few breaks and as you go round the corner the disk rubs against the pad. are they brembos or standard calipers fitted.

Will check that this evening so! It's not brembo's Quote Link to comment Share on other sites More sharing options...

Will check that this evening so! It's not brembo's do you know when the pads were last changed. you'll sometimes find as pads where out the piston that pushes the pad out and keeps it on the disc can bind in place. normallly its only an issue when you come to reset it and put new pads in because you'll need a new caliper. my guess is that the squeeze motion that puts the pad on the disc when you break isn't returning fully. make sure brake fluid levels are good as a lack of pressure may cause this. try and free them up witha lubricante, WD40 on a fine nozzle directed into the moving parts might do it. but it could require a dismantle and rebuild. but if pads are low change them at the same time and make it an all in one job. or even swap them over, i believe P17LT (think i got the name wrong(the one with the big mean green car ) wmight do brembo conversion kits or zmanalex is another person who might do a bremo conversion set. i think Zmanalex even has a store of old standard calipers etc so might be able to get a new one off him.

I've no idea when the pads where changed ...even if they ever have been changed. I'll take the caliper apart tonight and clean it up, normal to get a seized one (get it on the bikes from time to time). If I need to upgrade I'll go with StopTech brake kit and new rims Quote Link to comment Share on other sites More sharing options...
andlid Posted March 18, 2009 Author Share Posted March 18, 2009 After spending a good time taking off the wheel cleaning the caliper / cylinder & putting some grease on the back of the brake pads I put it all back together and rotated the wheel... SAME squeek that I've heard before is now there! EXCELLENT! (can now find out WHAT is causing it) find that it's one little lip of the brake pads shim's causing it! it's against the actual disc while I'm rotating the wheel/disc. Conclusion: My inner pads needs changing it's almost gone (the spacing) on the lower end of it (see picture) not sure why it's not worn evenly (?) When it's so worn the shim is against the disc as per design? (?) At least I know that it's not the wheel bearings thats gone Just need to go shopping for a new set of pads Found this TSB: http://www.350z-tech.com/zwiki/TSB_03-1 ... In_Reverse That applies to my car also... , btw do I actually need the shims? Thanks for all the input ! Spot on! Quote Link to comment Share on other sites More sharing options...
