Hofner Posted May 28, 2015 Share Posted May 28, 2015 Some advice needed for novice please, have 2004 nissan 350z jdm without bembo brakes. Drove 40 miles and noticed screetching from back wheel, then thought brakes were failing as pedal was very spongy and needed to be pushed full down to start any braking. Rear wheel was very hot and could feel heat from it about foot away. Called AA for a check, looked at pads and nearly worn to metal used tool to free calliper piston which has helped. When he he tried to spin the wheel it took a lot of force (without caliper on) which he didnt like and thought there could be somthing going on in the hub, has anyone expericenced this? And do i need a new caliper when pads are changed? Quote Link to comment Share on other sites More sharing options...
johnny cobra Posted May 28, 2015 Share Posted May 28, 2015 Could be wheel bearing ........... JC Quote Link to comment Share on other sites More sharing options...

GIXXERUK Posted May 28, 2015 Share Posted May 28, 2015 I would just change the pads but check the caliper condition when you do, I'm guessing the resistance is inside the hub so is most likely to do with the handbrake shoes ...... needs stripping and investigating http://www.350z-uk.com/topic/15976-how-to-change-non-brembo-rear-discs-pads/ Quote Link to comment Share on other sites More sharing options...
Sam Mcgoo Posted May 28, 2015 Share Posted May 28, 2015 I suspect the jdm rear callipers are the sliding pin type? If they are it will most likely be a sticky caliper, very common on Japanese cars with these types of brake. It will need stripping, cleaning and greasing at a minimum. Potentially a service kit to get it tip top again. Not too difficult to do yourself. You will have boiled your brake fluid too (hence the spongy pedal) so give that a flush/bleed with some fresh fluid while your at it.

Hofner Posted May 28, 2015 Author Share Posted May 28, 2015 Caliper looked ok with no deterioration to seal, sorry to ask lots of questions, any ideas on lack of initial braking? Car rolls foward a bit when handbrake on too Quote Link to comment Share on other sites More sharing options...

" When he he tried to spin the wheel it took a lot of force (without caliper on)" that made me think its not caliper related ? agree about the brake fluid boiled, probably discoloured Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted May 28, 2015 Share Posted May 28, 2015 You have been given good advice from the guys in there replies. I suggest that you at least act on some of it. Caliper strip and free off and grease up, check hand brake shoes etc. new fluid and flush. 2 Quote Link to comment Share on other sites More sharing options...

Car rolls foward a bit when handbrake on too possible fluid degraded and overheated worn pads, had a 350 and 370 and they both move forward slightly after the handbrake is applied Quote Link to comment Share on other sites More sharing options...
Hofner Posted May 28, 2015 Author Share Posted May 28, 2015 Thanks for info, have cleaned and greased calliper, which has made a difference, only 10 degrees Heat difference between rear discs after some vigorous braking. Will do new fluid Quote Link to comment Share on other sites More sharing options...
