sirhc Posted September 20, 2009 Share Posted September 20, 2009 My Sabre hasn't been stopping quite as well as it should, I thought the pads were probably contaminated with oil or water, a common problem on a CVR(T). This is what I found! Chris Quote Link to comment Share on other sites More sharing options...
Degsy Posted September 20, 2009 Share Posted September 20, 2009 No wonder it didn't want to stop. Technical word for those starts with f ends in d ...six letters:coffee::rofl: Quote Link to comment Share on other sites More sharing options...
sirhc Posted September 20, 2009 Author Share Posted September 20, 2009 Degsy, It did stop, the brakes were actually working, and they would hold it on a hill or on the neck of a low loader no problem! I tried doing an emergency stop and it was not as good as I thought it should be, otherwise I wouldn't have even looked at them!

Degsy Posted September 20, 2009 Share Posted September 20, 2009 Certainly does stand on it's nose when the brakes are spot on:-D Quote Link to comment Share on other sites More sharing options...
Jack Posted September 20, 2009 Share Posted September 20, 2009 OK - how can water contaminate them, aren't they waterproof? Quote Link to comment Share on other sites More sharing options...
sirhc Posted September 20, 2009 Author Share Posted September 20, 2009 Jack, They are designed to get wet, but not be submerged for any length of time. The gearbox bay of a CVRT is open to the elements at the top, but sealed at the bottom, so they tend to fill up with water. The water picks up any oil or hydraulic fluid which has leaked onto the floor and then coats the pads and discs with it. This is fairly common on CVRTs as if you leave the drain plate off underneath the gearbox then the fan draws air in through there rather than through the radiator and then your engine overheats!

Chris Well at least you know they are VERY easy to get at & replace Chris! Obviously, you are going to check the disc's before fitting new pads? :-D RE: Hull Drain Cover. I seem to recall when I had my Scorpion, there was a 'Valve' or manual hull drain plate/cover. I cant remember if you put your foot on a Button to open it via a cable. Or, it was on the front by the Tillers that you turned a screwed knob & it opened the valve to drain water. I think it was probably the latter. This was for the driver to operate after exiting water after the vehicle had deep waded, or swimming in the early days when they were all fitted with screens. Never had to look under the hulls of our Sampsons or Spartens. Only scorp's & Scim's! Yours may possibly not have this facility if it is a later manufacture & they did away with the valve? But, It did make life easier to drain the hull whenever you wanted! :yay: Mike. Quote Link to comment Share on other sites More sharing options...
sirhc Posted September 21, 2009 Author Share Posted September 21, 2009 Mike, Yes all variants including Samson and Spartan are fitted with this, but there is a gauze filter which gets clogged very quickly. As for the pads being easy to get at, they are not too bad, it's just a shame I can't locate a commercial equivalent part so have to pay dealer prices Chris Quote Link to comment Share on other sites More sharing options...

You dont always when your priority is a certain repair. You dont always have the time (Or can be interested, after all it's a Military bit of kit in your daily job!) to check out things other than what your tasked to repair. I can only assume that privately owned vehicles recieve the usual care & maintainance lavished upon them that an in Service example wouldnt! I know that You Chris, would clean your filters a Damm sight more regularly than a driver/ crew member would! You have to think that a Squaddie will only do what he can get away with. No more, if possible. His mind set is, 'It's not mine, & after all the Army is a big firm'. Anything goes wrong in general. HE, doesnt' have to put his hand in his pocket! As for private owners, WELL......As we ALL know. That's an entirely different matter!!! Good luck on sensibly pricing a new set of pads Chris! :thumbsup: Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted September 21, 2009 Share Posted September 21, 2009 As Chris will know we lost the steering on our Spartan 3 times at war and peace this year due to contamination and that filter being clogged up. I always put my foot on the drain button for a while before starting, but when you are in the drivers seat you can't tell if its draining or not!
