Why did they have to mess around with the handbrake, it wasn't broke so why did they fell the need to fix it? Evil or Very Mad


Miggit, the “E” brake on an 07MY> never go wrong sir... Granted on a sport & Disco they have a fair few problems but on the FF they are darn near bullet proof sir... Rarely need to fix one!

Sadly the old bus has to stand on my drive in all weathers as its to big to fit in my garage.

Anyway, started up as usual today, handbrake off (light went out), selected reverse, R/O/S pads wouldnt release. Tried on/off a few times with door open, could hear the stepper motor cycling, went forwards a few inches,
still nothing Big Cry .

Thought, oh well lets go for it, selected reverse with a few revs, the back offside proceeded to lift then heard a BANG Shocked , and pads had freed off. Went for a short drive, returned and gingerly tried it all seems ok.

Question:-
Are there springs that hold the pads against adjustable stops or is the electric motor hard linked to the pads, a schematic of that area would be much apperciated or point me in the direction of a pic.

NB: Now with colder weather coming ive decided to park using the auto box selector until i can sort this out.




Strider, your “E” brake has two functions sir... 1, it acts as a parking brake below around 10mph & 2, above a certain speed it then acts as an emergency brake! Try driving at 30+mph and flick the switch up! BRACE YOURSELF! and make sure you have no one following you!! As it applies the EBA and tries to force you & the contents of your car through the windscreen! So, do NOT let toddlers (that like to fiddle with switches) sit in the front when traveling Shocked

Its good practice occasionally to drive at walking pace and flick your parking brake on & off a few times as it cleans all the surfaces up and lowers the risk of it sticking on!

Hope that helps Thumbs Up

Yes it does very much Craig thank you Thumbs Up ,
I like the suggestion of operating it at walking pace to clean up the surfaces.

It takes me back to when i had my master cylinder fail on my 81' 4 door on the A1M (both circuits failed no fluid leaks anywhere, we diagnosed it as both sets of master cylinder seals had failed together).
I had to use the transmission brake plus changing down (5 speed manual) to slow me down from 70mph so i could go down a exit ramp and stop safely.
The smell of cooked pads when i eventually stopped was incredible plus the blue smoke coming into the cabin really focussed my mind Shocked .

I wonder whether the handbrake is actually the problem. My experience is the same as that of 47p2, in that if I put the car into the garage after washing (and particularly if wheel cleaner had been used) the pads can stick to the discs. I don't apply the handbrake when the car is in the garage as the floor is level, it is just in 'Park'. There is a bang when the pads release from the discs and as 47p2 says the best thing is to drive the car after washing to dry and clean the brakes and discs. Only Range Rovers since 1988

The bang will be the normal rear pads sticking to the disc surface as they pretty much hover over the disc... However i will say, the cheaper the pads, the more metal will be in them! And we all know what happens to bare metal with water on it! Rolling Eyes

Exactly which is one reason why manufacturers have to fit them. Haylands, You did ask what the point of them of was so I replied.

UPDATE:

Well this morning before going shopping I tried the above cleaning method at very very slow walking pace.
The car stopped like i'd hit a brick wall, do it at 30mph? NO WAY!!.
It certainly showed me how powerful and fast the handbrake operates. All good now Thumbs Up

I don't know the exact bit of legislation, I'm not that sad Whistle, but you don't necessarily need a hand brake but rather two methods of braking, I think. Basically if one system fails there's a back up. Its the same reason why we have "power assisted" steering on vehicles capable of >40mph or something. If the power steering fails you still have a mechanical linkage. I think a lot of this is legacy from when hydraulics in cars were new and untrusted.

I did hear something that JCB had to create a vastly complex steering setup for the Fastrac because it could do >40mph, and the tyres so big. The fact that this steering system is probably more unreliable than normal PAS is beside the point. Ed

I said "what's the point" not "why do we have to have one"

Doesn't matter how many bits of legislation say we have to have one I still can't see the point... just me expressing an opinion, if you want one fair enough....

As for it being a secondary breaking system, well.... try pulling yours on fully at 70mph and see if it is a worthwhile system...

The legislation to have them is ancient... decades before split braking systems, it is virtually impossible to be left with no brakes unless you ignore the onslaught of warnings and carry on driving.....

That's why I can't see the point.... Bit like the guy with the red flag.... technology moves on.... legislation lags behind... Pete

As i clearly said in my original post, i'm not judging just answering your question. I don't care whether you use yours or not, but the law clearly says you must.

"What is the point of one" and "why do we have one" mean the same do they not? Both seem like plain English, and they both mean the same thing.
Q. What's the point of a handbrake on an Auto?
A. The point is the manufacturer is complying with the law by providing one, and giving you the opportunity to comply with the law when using the vehicle.

Q. Why do we have a handbrake on an auto?
A. Because the manufacturer has to fit one to comply with the law and it allows you the opportunity to comply with the law when using the vehicle.


As I also said regarding it being a secondary brake, it's not going to do much but it's better than nothing.

I would recommend re-reading my post as you obviously took offence to my non-aggressive and non-judgemental comment!

Well if i recall correctly (i can't be bothered to look), the highway code says words to the effect of "you MUST apply your handbrake when leaving your vehicle". So i'd say that still says you need one, although you're probably right about MVC&U also saying you have to have a secondary system too.

Opppps Sorry Stan Embarassed

Regarding the handbrake debate, who gives a S****, lifes too short Rolling Eyes .
Cars have to have them, end of argument.

Also, speaking from PERSONAL EXPERIENCE , my transmission brake saved my life and enabled me to drive home safely and stop after a fashion at roundabouts and junctions.
One thing it taught me the unexpected can happen and im glad i had a handbrake that day.
NB: The mechanic i spoke to thought that as it was an original m/cylinder on the car, and in those days I used to bleed the brakes using the brake pedal, he thought the piston seals were damaged when overtravel occured by the seals passing over a wear ridge in the cylinder bore and all failed at the same time.
