Annoying brake rattle


rider

Recommended Posts

I have an annoying metallic rattle that comes when travelling over rough roads that goes away as soon as the brakes are applied. Garage can't find anything likely to be causing it - anyone got any suggestions or ideas on this? The car has just passed it's MOT without any reports.

Discussions with Porterfield Brakes have petered out on the anti rattle springs/clips when it transpired my brakes are of the Japanese variety and the picture shown here is for the UK 4 pot variety. Does anyone know of any companies supplying springs or clips to retain the pads for the 2 pod Jap spec calipers?

I called the number you provided but it was busy yesterday and hung up with a call back later message. I googled the number and it came up as Porterfield Brakes so I assume I've been in e-mail comms with Paul but that kind of ended when he pointed out that the pic was UK spec brakes and there wasn't anything similar for Jspec. Looks like it'll have to be expensive toyota as I can't find any retailers from a web search.

 

Thanks for the help, at least i know what I'm looking for now.

Just as a final note on this thread for anyone else suffering from banging pads there are apparently sprung clips that I need to replace behind the pads so I'm looking around for those at the moment. I did come accross an interesting post on the land rover forum on the same topic. The solution there was pack the pads in with lots of grease backing them and apply gaffa tape around the retaining pins. They are clearly a very rustic lot the land rover crowd. I did look for a post detailing how to work windscreen wipers with lengths of string but they don't seem to have thought of that yet!

Sounds like you need the anti rattle SPRINGS which after braking push the pads away from the disc so to stop them catching the rotating disc and moving in the calipers and squealing either against the disc or against the piston. It is worth going to your local toyota garage and getting a new sets of;

 

Anti rattle springs 2 per corner (thin elongated horseshoe looking links between the two pads)

Anti rattle SHIMS 2 per corner (one on the back of each brake pad, normally when attaching you put a THIN! amount of copper slip/grease between it and the back of the brake pad)

Brake pad retaining clips 4 per corner (2 per brake pad they hold the pads snugly against the cradle/caliper brackets)

 

Also since you have import (Jspec) brakes check for stuck slider pins (plenty of threads on here with pics if you use the search function) as they can cause uneven pad or disc wear, even disc warping which would cause occasional squealing. Also check your dust shields aren't fouling on the discs as this will cause squealing.

 

If you go to toyota note down the part numbers then try the traders on here to see if they can better MR T's prices however for these relatively cheap components I think MR T will win. I won't name any names but for 4 anti rattle springs I got a quote of ~£50 off a trader from here, But Mr T did them for around £5.
