Paul64 Posted September 23, 2009 Share Posted September 23, 2009 Hi, On a long distance trip at the moment and noticed a lot of heat coming up from the drivers seat box. Had a look underneath but can't see anything wrong. However, I noticed that the low box/Diff lock gear stick and surrounding metal is hot but the main gearstick just slightly warm. Is that usual when running at higher road speeds? I have a Defender 110 CSW, 200Tdi and I'm cruising at about 65mph. She spends most of her life off road, so such a long road trip is rare. No problems with performance, she is just throwing out more heat than I have noticed before. Thanks in advance, Paul Quote Link to comment Share on other sites More sharing options...
Godlykepower Posted September 23, 2009 Share Posted September 23, 2009 Yep its normal. It is the heat generated from the transfer box. Quote Link to comment Share on other sites More sharing options...

GBMUD Posted September 23, 2009 Share Posted September 23, 2009 Hi Paul Close your windows and open your vent flaps. The windows create a vacuum inside the car and pull hot air into the cabin making it uncomfortable. Chris Quote Link to comment Share on other sites More sharing options...
mmgemini Posted September 23, 2009 Share Posted September 23, 2009 As Chris says...I can tell you it works at 35De C ambiant. Fit an X-Eng disc handbrake. I'm sure most of the heat generated comes from the handbrake drum. miker Quote Link to comment Share on other sites More sharing options...
Paul64 Posted September 23, 2009 Author Share Posted September 23, 2009 Thanks guys. Well, I've learned something new today regarding the vents. I always keep vents and windows open to let the air pass through. I will try the vents only tomorrow as I still have another 400 kms to drive. It was about 28 0C today and it must have been double in the cab. My ar*e was cooking! So do you think this is handbrake rather that transfer box Mike? Or is it a combination of the two?

Guest otchie1 Posted September 23, 2009 Share Posted September 23, 2009 A properly setup LR drum handbrake shouldn't rub at all and so shouldn't be generating any heat. You're more likely to get heat build up from a transverse disk brake arrangement where the pads float continually on the disk. With a seized caliper I'd judge that to be a fire risk.

Cheers, Paul Yes Paul64I do. Why. Because on our first to southern Africa trips the heat from the seat box burnt my legs when wearing shorts. Aftyer the first trip I fitted an oil coolet to the gearbox. Still excessive heat. On our last trip with the X-Eng brake fitted there was very little heat even at 45 deg C ambiant. mike Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 23, 2009 Share Posted September 23, 2009 The handbrake drum being warm after a trip is normal, it being too hot to touch...I'd be worried of excess friction at hand. Have a feel underneath after a drive Quote Link to comment Share on other sites More sharing options...
Paul64 Posted September 23, 2009 Author Share Posted September 23, 2009 Thanks again, I will check it tomorrow. Several months ago the handbrake was pretty ineffective, so someone adjusted it for me. It works fine now, but is it possible to over adjust so the pads are touching the disc? There doesn't feel like any drag.

landmannnn Posted September 23, 2009 Share Posted September 23, 2009 The gearbox generates heat but since it is bolted to the engine it will soon warm up from conducted heat from the engine. So yes, they do get hot and then radiate heat to the uninsulated seatbox. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted September 23, 2009 Share Posted September 23, 2009 You mean touching the the drum, and yes it is possible. The shoe position is adjusted behind the drum similar to a normal wheel brake, and the handle throw is adjusted by the fixings on the end of the cable. Shoes should be just shy of touching the drum, and the handle should begin to engage at the first click Quote Link to comment Share on other sites More sharing options...

So is the position of the shoe will be a case of trial and error as you can't see the actual position when adjusting? My LR is not hindered at all when rolling forward without the handbrake on? When I get going this morning I will check out the heat from the handbrake drum. Cheers, Paul Quote Link to comment Share on other sites More sharing options...
bigbeast Posted September 24, 2009 Share Posted September 24, 2009 what about insulating inside the seat boxes, surely this will disperse some of that heat, maybe foil backed foam, etc?? Quote Link to comment Share on other sites More sharing options...

Cheers, Paul If your car is rolling freely it sounds like the handbrake is correctly adjusted. Correct adjustment procedure is to screw the adjuster in until it's tight and the brake drum is locked, then back the screw off until the drum turns freely. Of course this needs to be done with a rear wheel jacked up, the handbrake off and the car suitably chocked to prevent it rolling. HTH Mark.

Thanks for the idea. Didn't get to check the handbrake drum. It was chucking it down with rain for the full 400km's. That said there was little heat today, so maybe the cool air was cooling things down. Quote Link to comment Share on other sites More sharing options...
