parthiban Posted July 25, 2012 Report Share Posted July 25, 2012 Toyota want over £200 a caliper and I don't want used ones as I'll probably get the same problem so who else sells decent replacement calipers? From my experience with the Lexus forums, the only option is to replace with genuine parts. However many have had success with servicing the existing ones. Another thing, if there is no play in the wheel is it still possible for a bearing to be on it's way out? My wheel had no play in it despite the collapsed bearing, so yes I'd say it is possible.

Also going to check the hoses in case it might be them. My wheel had no play in it despite the collapsed bearing, so yes I'd say it is possible. How did you know it was the bearing if there was no play? If I'm still not sure when I've had another look I'll have to get it looked at for another opinion.

Also going to check the hoses in case it might be them. Agreed. Like I said many have had success with refurbishing them so well worth trying that first. How did you know it was the bearing if there was no play? If I'm still not sure when I've had another look I'll have to get it looked at for another opinion. I didn't. Few people I spoke to thought it was the tyres or the brakes but there was nothing obvious wrong with anything. Ended up taking it to Lexus once I had exhausted other options and they took it apart and said the bearing had collapsed, wouldn't even let me take the car away as it was unsafe. It was only a few months old though so they replaced it free of charge but there really was no sign other than the noise that it was the bearing at fault.

Rich Posted July 25, 2012 Author Report Share Posted July 25, 2012 Was it making a noise like a bearing though cos the noise I've got doesn't sound like it is? Quote Link to comment Share on other sites More sharing options...
parthiban Posted July 25, 2012 Report Share Posted July 25, 2012 Was it making a noise like a bearing though cos the noise I've got doesn't sound like it is? Can't see your video at the mo, will check it out when I get home tonight, but it was basically a mild humming/grinding noise. Haven't had a failed bearing before so wasn't sure what it should sound like, but others who got in the car and heard it weren't convinced it was the bearing.

Rich Posted July 25, 2012 Author Report Share Posted July 25, 2012 I've only ever had one bearing go before and that was on the rear of an Escort, it was very loud and noticeable in a straight line, nothing like what I'm getting now.

Mine wasn't loud at all, wouldn't hear it if the radio was at reasonable volume. Also only made noise when turning in one direction (can't remember which), in the other direction or going straight was completely silent. No difference in feel through the steering wheel either. Barring the mild humming sound, the car felt absolutely fine. Hence the surprise when they told me the car was unsafe to drive! Quote Link to comment Share on other sites More sharing options...
Rich Posted July 25, 2012 Author Report Share Posted July 25, 2012 I suppose it's possible I have a bearing going as well as the binding caliper!! Quote Link to comment Share on other sites More sharing options...
parthiban Posted July 25, 2012 Report Share Posted July 25, 2012 I suppose it's possible I have a bearing going as well as the binding caliper!! It's definitely possible, worth checking - do you have a Toyota dealer nearby who can check it over without charging? At Lexus they're normally happy to investigate things without any charge but not sure whether that's specific to that dealership or if it's a general thing.

Rich Posted July 25, 2012 Author Report Share Posted July 25, 2012 Ok driving home I swear I got that burning smell again when stopping at the lights. Got home and I can see where the pad has been rubbing. The car has been sitting in the sun all day and with this heat could the slider pins or piston be expanding too much stopping the caliper from working properly? It slides on the pins ok when cold.

liner33 Posted July 25, 2012 Report Share Posted July 25, 2012 The caliper gets much hotter in use than it would ever get sat in the sun Quote Link to comment Share on other sites More sharing options...
Rich Posted July 25, 2012 Author Report Share Posted July 25, 2012 True but what about the rubbers and hoses etc. What about using too much grease on the slider pins? I read that can cause a vacuum if too much is put on, although I only put a thin smear on. Quote Link to comment Share on other sites More sharing options...
Rich Posted July 25, 2012 Author Report Share Posted July 25, 2012 Both these videos I took tonight after removing the calipers. The NSF wheel I couldn't really move with the caliper on, once I took it off it spun ok but there is a noise, hopefully you can hear it in the video. When fitting the caliper back on I pushed the piston in but forgot to take the cap off the resivour but it went in with no effort at all, is this normal? http://www.youtube.com/watch?v=qTO9w3XB4Aw& The OSF wheel was abit concerning cos after taking the caliper off I had problems turning the wheel and was getting this noise. I couldn't see the wheel rubbing/catching on anything so not sure what's causing this. Funny thing is taking the wheel off and just spinning the hub with the disc on was ok, there was no resistance! Maybe the weight of the wheel was affecting it. http://www.youtube.com/watch?v=Pdygo2Ij_j0 Think this needs to go to WIM now, I don't have the time or patience to sort it out. Getting really hacked off with this car now, also spotted coolant dripping from somewhere! So much for Toyota being reliable! Quote Link to comment Share on other sites More sharing options...
Rich Posted July 26, 2012 Author Report Share Posted July 26, 2012 NSF has a shot wheel bearing and binding caliper, great! We're not sure why the caliper is binding cos the slider pins and piston are working ok. Caliper might need a rebuild but I'm getting the wheel bearing sorted first. The OSF was ok when it was on the ramp though. Really not sure what happened there in the video, when I removed the caliper and put the wheel back on I made sure nothing was in contact with the wheel. But on the ramp today it didn't make that noise! Quote Link to comment Share on other sites More sharing options...
liner33 Posted July 26, 2012 Report Share Posted July 26, 2012 A binding brake can cause a wheel bearing to prematurely fail the heat buildup breaks down the grease Quote Link to comment Share on other sites More sharing options...
Rich Posted July 26, 2012 Author Report Share Posted July 26, 2012 I think the bearing was already going as I 've had this noise for months. The binding brakes has only happened recently. The noise has started when driving in a straight like though so that's probably why. Quote Link to comment Share on other sites More sharing options...
parthiban Posted July 27, 2012 Report Share Posted July 27, 2012 Good to know what it is now, hope once these are sorted out that'll be the end of the problems Quote Link to comment Share on other sites More sharing options...
Rich Posted July 29, 2012 Author Report Share Posted July 29, 2012 Hopefully, I want to drive the car properly again, it hasn't felt right for ages if I'm honest but really did think it was down to the tyres still being the winter ones. Bearing is really bad, on Friday I could hear it in a straight line so getting worse quickly. Getting to WIM first thing in the morning so hopefully fitting it will go with no problems. Also getting the flexi hose for the brake replaced so hopefully that stops it binding. Quote Link to comment Share on other sites More sharing options...

Rich Posted July 30, 2012 Author Report Share Posted July 30, 2012 Bearing has been replaced and it's quiet as a mouse now, so that's one thing sorted. The flexi hose was replaced and while it's improved the binding it is still there so looks like I will end up replacing the caliper. It's a shame the only available brake upgrade for this car costs £1,000!! The Toyota calipers just don't seem that good as alot of owners get this issue.

Tony Posted August 6, 2012 Report Share Posted August 6, 2012 Glad the noise is sorted, was it just the one bearing? Quote Link to comment Share on other sites More sharing options...
Rich Posted August 6, 2012 Author Report Share Posted August 6, 2012 Yeah just the one side, just gotta keep an eye on the brakes now. Quote Link to comment Share on other sites More sharing options...
Rich Posted August 14, 2012 Author Report Share Posted August 14, 2012 Great got another noise when steering right now, fine in a straight line or left. I think it sounds like a humming or whirring noise? It doesn't seem to do it in sync with the wheel though just a continuous noise. I haven't used the car for the last 9 days until yesterday but didn't notice it on the short drive I did or I had the radio on too loud. I'll try and record it on the way home from work. Really starting to hate this car! Quote Link to comment Share on other sites More sharing options...
