You don't give a year of manufacture, so we can't really judge if this sounds right.

Highly unlikely that all pipes need replacing, but in practice when you start to undo scabby brake pipes the next section gets twisted up as the joints are corroded solid and you can end up doing near enough the lot, if the flexibles need replacing too then that cost could easily be about right.

Its good preventative maintenance to keep the pipes well greased/waxoyled from new, if well looked after they should last the life of the car, it can mean serious dismantling of the suspension to replace some rear pipes especially, often enough the rear subrame/suspension has to be dropped to gain access.

Most owners neglect brakes, the most important part of a car, until they fail the MOT, they need regular care and attention.

I'd be inclined to get a second opinion on your car and then compare.

Difficult one, you haven't got much manoeuvering room there.

Unless you have a very good chap whom you trust on tap who could trailer it out and fix it for you cheaper than the quote you've had then it looks like one of those to take on the chin.

On the good side better it burst on the rollers than in a panic situation on the road.

Must have been badly neglected however for this to happen.

It cost me around £370 to replace the rear brake pipes and flexi hoses on my previous BMW, but that included a new rear brake caliper. The fuel tank had to be dropped as the pipes go over the top.

The price doesn't seem unreasonable to me considering that all of your pipes need replacing, but I don't know how involved the job is on the Accord. I do know that they are prone to brake pipe corrosion, as are many cars, Mk 3 Mondeo's being one.

The materials are cheap, most of the cost will be labour.
