Brake pipe corroded and Front Suspension arm brush worn cost

"Brake pipe corroded, covered in grease or other material" should be perfectly safe to drive. If the pipe was actually rusted, then the advisory would be "Brake pipe excessively corroded". Its probably just covered in crap. You should ask the garage what the actual issue with the brake pipe is.

If it is rusty then do get it replaced. I had a rusty brake pipe and it collapsed while I was driving, pretty scary experience when you suddenly lose your ability to brake!

But if it's not actually very rusty then no point replacing it, waste of money.

Edit: Actually it wouldnt be an advisory if it was excessively corroded, it would be a fail

Meanwhile, a friend had a brake pipe burst on the MOT ramp... having never had an advisory on it before.

The MOT fail criteria is for a pipe to be corroded to two-thirds of its original wall thickness, having lost about 0.25mm. That's obviously impossible to measure in-situ with any degree of accuracy.

So most testers will flag up anything that raises their eyebrows as grotty, reserving a fail for pipes that they really don't like the look of one bit.

I think we can assume the mechanic that's quoted has seen the pipes in question.

But he hasn't explicitly said it's corroded.

All cars these days have dual circuit braking so one pipe collapsing would not mean you lose the ability to brake. It must have been on a 1970's car?

In The Olden Days, dual circuit brakes were dual circuit- I think Volvo had this, so both front brakes worked with any one broken pipe, but at lower efficiency.

Then we had diagonal split, so a broken pipe meant one front always worked, and now we have front/rear split, so if a front pipe bursts you might as well use the handbrake, stopping on just the rears takes forever!

I think in general front wheel drive cars use diagonal split, and rear wheel drive cars use front/rear.
