Hi Darren, If the brake cylinder in that wheel has seized it will need to have the drum removed which will not be easy. Chock the wheels, make sure the parking brake is fully released and loosen the lug nuts. Jack the vehicle and remove the wheel. Open the bleeding nipple at the back of the splash plate, thereby releasing the pressure of brake fluid. If the wheel rotates freely when you do that, the problem is with the master cylinder which will need replacement. If the wheel does not rotate after doing that work the wheel backwards and forwards until it rotates. Once it has become free, you should be able to work it off. When it is off you will need to disassemble the brake assembly. Before doing that make a detailed sketch of the whole assembly before taking anything off. Once the assembly is removed and you've grazed your fingers and cussed enough, remove the wheel cylinder and free the pistons and disassemble by removing the pistons. It would be a good idea to replace the cylinder but if it is not scored inside replacement brake seals will be in order. Make sure you fit them the correct way around and reassemble after installing the new brake seal kit.
Adjust the brake so that travel is even. Once done bleed all four wheel. Begin the procedure at the furthest wheel from the master cylinder and work closer each time, bleeding each wheel until all signs of air have been expelled. Test the brake pedal for firmness and then fit back the wheel, lower the jack and complete the diagonal tightening procedure. Test the brakes by pressing the pedal. If the pedal sinks to low bleed again. In a safe place, test do a road test to make sure the brakes are correctly adjusted. When finished go inside, put your feet up and have a long cool drink, or a cup of coffee, tea or anything else as a reward for your labour. Best Regards John
