I have an Invacare 450 hydaulic lift and the brake is stuck on one of the castors. How can I release it I've tried forcing it without success.

hi Helen, firstly the scooter will lock up after a couple of metres , that is by design to stop you rolling down a hill etc ..

Now if the scooter is hard to push even in freewheel, means the brake has either decided to seize (lack of use , been in storage ) or has become damage. The mechanism for releasing the brake has become damaged . brake removal recommended then try to push the scooter , if it 's okay then its the brake if not , it could be the coupling between the motor and gearbox has failed or the gearbox itself has a issue,.

Regards
Rob

Make sure the steering wheel is not close to one of the "steering wheel position lock stops" before turning the key.

There is some castor in the suspension. (all this means is that the wheels will try to return to straight ahead when the steering wheel is released. It has to do with weight of the vehicle and suspension geometry).

There are locking points in the steering system so that if someone hot wires your car they will only be able to drive around in circles. How far will they get?

Your key may be getting stuck in between the return tendency of the castor and the locking notch or dog or whatever.

Turn the wheel to lift up the front of the car slightly (that means more toward not straight ahead. It may help to think of the steering wheel as a jack for the front end of the car).

Once you lift the car off the key it should turn and come out easily

This happens for a lot of reasons. Try using something like a small hammer to tap the release lever loose. If the bar that slides to hold the footrest is bent or badly nicked, consider replacing that part from a place like Ocelco.com.

THIS IS A COMPRESION RELEASE IT IS FOR SLOWING DOWN FASTER OR FOR CRANKING COLD.USE IT TO GET THE PISTON TOP DEAD CENTER AND THEN CRANK. OR WHEN YOUR RIDING YOU CAN USE IT TO SLOW DOWN WITHOUT HITING THE BRAKES....

If you have made sure that the freewheel levers are in the drive position and after turning the power on and you are still getting the barke error then the motor and brake assembly will have to be checked by a tech and possibly have to be replaced There is no self fix for your problem Sorry Hope this helps you

Hi Luce n Steve, To quote JC at Photo.Net: "sometimes the rewind function "gets stuck" if the camera thinks a previous rewind did not complete successfully. The solution is to reset it by forcing a rewind operation. Just press the two rewind buttons simultaneously: on the left side of the lens and just behind the shutter release. (They are marked and the manual explains how to force a rewind.) I did exactly this, and my next roll of film loaded without problems." Hope that help you folks.

Hi. I have had a few scooters that have had this problem after sitting for a while. The brake lining is stuck to the body of the brake assembly. When the brake is energised by the controller, it can't release.
De-clutch the machine like you did, and try rocking the machine back and forth. If this doesn't work you might have to have a new brake assembly fitted.
The wheels turn in opposite directions, because the drive is through the differential unit in the rear axle. Even a car will do this if the driving axle is raised in the air.
I have also had a few cases of stuck motor brushes in these machines, but from your description, I would say it is the brake assembly.
Good luck. Neil.
