Petrolhead Posted June 15, 2004 Share Posted June 15, 2004 When braking hard (straight line) I get a knock from behind the seat. Could it be a worn bush (Done 5500 miles) and if so any advise as to which it possible is? Now with SL No 148 Link to comment Share on other sites More sharing options...
JAG Posted June 15, 2004 Share Posted June 15, 2004 Does the knock occur as you begin to brake, sometime during the stop or at the end of the stop? What type of rear brake do you have, drum or disk? Is this a live axle or De Dion car? Justin A closed mouth gathers no foot. Link to comment Share on other sites More sharing options...

Badger Bill Posted June 15, 2004 Share Posted June 15, 2004 Is there someone in the boot? Only kiddin' 😬 BB edited to say that it is difficult to get a knock from behind when you are infront... Edited by - Badger Bill on 15 Jun 2004 12:17:07 Edited again to say that it is easy to get a knock from behind when you are infront, however it is difficult to knock from behind when you are in front. You know what I mean. Knocking from the boot when you are in the engine bay, but the noise was in the boot, and you need arms like Mr. Tickle to do that. Not that Mr. Tickle isn't in your engine bay, but you would see his arms going past, and so it would be obvious. That, and the fact that he is fictional, would point more towards that it is not Mr Tickle in you engine bay. Incase you were wondering. Ah, time for the medicine again.

Petrolhead Posted June 15, 2004 Author Share Posted June 15, 2004 Possibly something, oh yes cheese 😬 Now with SL No 148 Link to comment Share on other sites More sharing options...
Myles Posted June 15, 2004 Share Posted June 15, 2004 Check the pad wear - especially if you've got standard rear brakes and 'rigid' hoses. As the pads wear down, the sliding caliper gets closer and closer to the suspension arms under braking and can eventually touch. The rigid brake lines don't help matters - they tend to promote slightly uneven pad wear (inners wear more than outers).

prs Posted June 15, 2004 Share Posted June 15, 2004 Might be worth checking the fuel filter to make sure it's securely attached as that is right behind you or at least it is on mine which is a 1.6K, otherwise carry out a complete torque check on all bolts (personally I do this twice a year for piece of mind) including the caliper mountings.

Petrolhead Posted June 15, 2004 Author Share Posted June 15, 2004 Cheers guys, will check this out Now with SL No 148 Link to comment Share on other sites More sharing options...
Myles Posted June 15, 2004 Share Posted June 15, 2004 Ah, sorry, re-read the post (I've got rather small fonts on the screen at the mo....) 😳 Could it be the seat-runner? Mine sometimes clunks forward fractionally under heavy braking... Keep BC free and open for ALL.

Petrolhead Posted June 15, 2004 Author Share Posted June 15, 2004 Nice thought Miles but mine also does that but i can feel/sence the seat moving. I am shure its not that but excellent thought Now with SL No 148 Link to comment Share on other sites More sharing options...
JAG Posted June 15, 2004 Share Posted June 15, 2004 The late occurence generally rules out anything loose (this would move as soon as decel' began) and rules out most things related to the brakes and suspension. Unless; do you get any noise when you accelerate? The torque being opposite to braking torque should cause any worn bushes to move in the opposite direction but will make the same noise.
