| underbody/enginebay cleaning |
|
has anyone got advice with regards to cleaning the disco particularly after a run in the sand or mud. i have given it a good clean of the underbody but plan on getting under there again and checking out any areas that sand may have remained.
i read up on lanlin spray. it is meant to be sprayed pretty much everywhere underneath. is there anywhere that would cause negative effects if i sprayed it?

Not answering your question  , but just been on Landrover Experience course and the instructors were adament that I should not use the handbrake  Without admitting I knew of the D3 EPB problems, I questioned the issue and they confirmed that with dirt from the offroad course the handbrake would stick & cause problems! Bit concerning as LR have known of the problem since the D3 and it's fairly obvious that an owner expects to be able to use their handbrake, and if it is an offroader to be able to use it without special treatment!
They were relying on leaving the car in "Park", which I'm not prepared to do... imagine having to admit to your insurers that you left the car without the brake on - if the EPB fails to function properly & LR claim it is not covered by warranty terms then a "not fit for purpose" issue will arise for the supplying dealer who can sort it out with LR Would help though if there was some underboady cleaning or protection treatment that could be used to minimise the problem.

that is amusing. so go for a great trip off road in the disco, but be prepared for the park break not to function correctly afterwards. did they show where in the EPB is located. I can only guess that by locating it and using some kind of prtectant such as lanolin to stop anything from getting in to it may assist in prevention.

Hi DiscoDC,
As long as you keep it away from any friction surfaces, you should be fine.

They just said that the dirt/mud from off-roading got into it & caused it to jam on, so their solution was never to use the parking brake
Perhaps someone else on the forum can confirm the location of the offending components so they can be pressure washed down on a regular basis?

The mud and dirt gets into the handbrake drums, which are inside the rear brake discs. It then gets between the brake shoes and the drum and grinds away the friction material.
This means that that brake quickly goes out of adjustment, and the cable pull needed by the actuator (up in front of the spare wheel, big black box with a bowden cable each side) will eventually reach the limit of the actuators travel, and the protection clutch will slip. This is to prevent the motor burning out, and it makes a hell of a screaming/grating noise. Repeated use in this situation could damage the actuator.
The only way to properly sort it out is to remove the rear brake calipers, remove the rear disc's, dismantle the shoes, clean, lubricate, reasssemble, adjust. Many just do the final adjustment to stop the screaming.
Failure to clean and lubricate can cause the brake to stick and bind. This can cause allsorts of problems. It again will wear the shoes out, and make the brake go out of adjustment. It can cause squeeking from the rear brakes at low speed. It can also be dangerous at speed if the binding causes a heat build, which can cause the the friction material to detach from the shoe, and jam. The symptom for this is a sudden vibration, that may come and go when you drive at speed, a hot rear wheel, excess brake dust on one or both rear wheels.
You can't jet wash the parking brake, it is inside the rear discs.
End of lesson

If I understand this right, a "fix" for the EPB problem with mud is to:
1. Install a low-pressure air compressor somewhere in the engine,
2. Install a air drier on the outlet of said air compressor,
3. Run lines from said air drier to both EPBs and somehow connect air to the inside of the brake drums, and
4. Put up with bubbling from brakes when in mud and laughter from drivers of other brands at the bubbling 
At least it might keep the mud out of the brakes  . Any other suggestions are welcome - can't be any more rediculous that having EPBs that have a bad failure mode if exposed to mud or dust!
No doubt BBS SPY would come up with a means of getting the onboard computer to monitor this new system. Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

so much for just giving the car a once over with the hose after a beach run. or then again, more attention has to be given to the rear brake disks to clear out all the crap.

Resurrecting this old post as I'd also like to know if "anyone got advice with regards to cleaning the disco particularly after a run in the sand or mud", particularly for the engine bay.
Seems this turned into a EPB post which was all that bad really..lol..some good info.
Is there anything to be aware of when cleaning/degreasing in the engine bay other then watching out for electrics etc.
Cheers guys.

The easiest option would be for lr to move to a normal car setup, ie braking mechanism on the caliper as drums are a stupid technology.
If someone comes up with a kit to replace the epb with a manual system they will be set for life on disco, ss, and ff landrover products IMO  FFRR Owner, very nearly became a D3 owner
