There’s absolutely no correlation between body styles (hatchback versus sedan) and the propensity for leaking brake cylinders. The difference between your mum’s and your previous car and the Tiida is probably all down to the quality of the parts, not whether it’s a hatch or sedan.

Brake cylinders leak when the rubber seals inside them fail. But because the cylinder is hidden within the brake drum, a leak is often only found when the car is being serviced or inspected for a roadworthy certificate. And as you’ve found, that’s often too late to prevent the brake shoes becoming contaminated by the leaking brake fluid.

The best way to avoid leaking brake cylinders is to have the braking system flushed regularly. It’s also important to replace any leaking wheel cylinder with a good quality unit. I’m tipping the reason your cylinders failed the second time was because the original ones were replaced with cheapies (possibly sourced online) which simply weren’t as good as the Nissan originals. Always beware when buying replacement parts of any sort that they’re good quality, particularly when it comes to critical safety systems like brakes.

There could be a number of reasons the steering is rattling and you really need a mechanic to listen to it so the cause can be isolated. It could be from the top of the column, the bottom of the column, the steering joints, or if it's down under the front of the car it could be the steering rack. Before you fix it you need to know where the rattle is coming from. The lights coming on could be an electrical connection problem.

Just about every small car will match the space of the Tiida so you have two choices, go for a class leader such as the Mazda3 or return to Nissan for a value deal on the Pulsar. The Mazda gets The Tick but the Nissan is very good value.
