try it!

but dont dip the clutch. if you start to move the natural thing to try is to hit the brakes, but remember you will have little, if any servo pressure. in this instance yank the h-brake.

lol true enough answer.

I just seem to think this 'method' doesnt really obey the laws of physics!

As you say tho i sould just try it!

I would be inclined (no pun intended!) to agree with DanGB that it will be first gear if facing uphill and reverse if facing down so make sure it is a clear hill before attempting to try it!:doh:

Handbrake Problems!

Thanks to all. The dealer has said they will replace ratchet, cable and clamping mechanism at rear wheels. Parts should be in next week. Going to talk to SEAT about compensation but don't hold alot of hope. The important thing is it will be fixed and its booked in at the body shop for the 30th April. :clap:

That is good news on getting it replaced. it is in your favour in regards to compensation as it was the faulty ratchet mechanism that was at fault and ultimate cause of the damage.

so would i be correct in thinking if i park on a hill, leave the car in first, then release the handbrake it wont move?

sounds crazy to me lol

Why do you think the car slows down so quickly in low gears when you take your foot off the gas? :p The kinetic energy of the car has to turn over the entire engine with no power.. Or something like that! :blink:

It is probably there is not enough potential energy being released by the stationary car on the hill to convert into movement (kinetic energy) to overcome the friction of wheels, bearings, transmission, clutch, the amount of braking pressure applied (if any i nthis case), compression of cylinders and also the gearing ratios probably don't allow enough torque to be produced to turn over the engine!! probably talking complete B***ocks but correct me if any wrong, long winded yes, still typing... need to stop....

Ps. more physics. KE = 1/2*m*v² PE = m*g*h Mechanical Energy = PE + KE

:headhurt: I thought I'd forgotten those equations forever! I never was any good at A-level physics!

I think your problem is more likely to be the discs as opposed to the hand brake lever dropping. I have had this problem on a few cars now (Current car which is a Touran, Impreza and a Rover 420 SLI). Each car had rear disc brakes and like many have said, as they cool, away goes the car. Drum brakes dont do this as the play on the shoe grabs the drum as it trys to roll making it brake harder.

As for leaving it in gear, I am sure you know how hard it is to bump start a car, and how if you dont move fast enough before engaging a gear it stutters to a halt, imagine putting gear in and then pushing the car, you are never going to move it even on a hill (we are not talking a cliff here).

I bet as this has never happened to you before, you havent owned many cars with rear discs. You must put handbrake on alot harder and you cna ensure its on by pushing against to test it doesn't drop (as your dealer will do)

I doubt your going to get anywhere as a warranty issue.

Hope this is helpful

First or reverse doesn't really matter, it's about the lack of mechanical advantage that the car has over the transmission and engine. For example, SAABs have to be put into reverse before you can remove the ignition key.
