Can you solve these teasers found in the GCHQ puzzle book?

General hint: Many of the puzzles may look more intractable than they really are. In a lot of cases the trick is to approach the puzzle with the right mindset – in other words to think like a GCHQ puzzle setter. So for example when looking at a set of words, don’t think of them as words, think of them as a set of letters. And when looking at a set of letters, think whether they could be converted into numbers. And when looking at a set of numbers, think whether they could be converted into letters.

A poem

Whilst driving recently my car felt weird.

The steering failed and off the road I ______.

A gentle stop was not on the agenda.

I bruised my leg, and gosh did that feel ______.

I ______ right by the vehicle till the AA came along.

They spotted that the brake alignment had been set up wrong.

The mechanic in the garage said he would have to _____

and then replace the brakepipes, back into their groove.

He tested them and it turned out that the test results were poor.
