Handbreak

Ive got a standard discovery 1, 1991 h reg runing on road biased tyres. i went off roading on the weekend completing some greenlaning, and encountered some situations where i needed recovery from other club members. on completion of greenlaning i went to hose the vehicle down before my return journey home. on hosing the vehicle doen i spent attention to the brakes and making sure the calipers and disks where free from mud. on finishing cleaning these areas i went on my return journey home of 40miles. the brakes did return back to soom normility but the hand brake light did remain on on the dashboard on the return journey, even though it eas off and the vehicle ran easily. is this an issue that will go away with time or need addressing? or do i need to take the rims off the vehicle and clean the calipers more throughly with a karcher

The Handbrake is the drum on the back of the transfer box and is a drum type brake. Its 'locks' the transmission and is not related to the brake calipers ... I have a similar problem with the dash light staying on .. a few levers of the handbrake and it does go out .. i just put it down to a dodgy switch as the handbrake does disengage ...

yes it does engauge, and hold the vehicle once parked up, or for hill starts, but the light remains on even when off. i did get beached when off roading and have to dragged to a point where the tyres gripped again, last thing i want to do is carry on driving the vehile and do damage to the handbrake. the light had previosly extenguish the day before my greenlaning once the handbreak ws released, therefore did my beaching and be dragged out had any undue effect on the handbreak or is an easy fix and can be ignored?

thanks
