Following the engine change in my 306, the brakes seem to be very... err... crap to put it mildly. I know the brakes on a diesel work via the vacuum pump which is fully connected to the new engine and I presume should be fully working since the new engine had only 83k miles...

It feels like the brakes aren't biting, like the feeling you would get if you had drums all round rather than discs up front.

Does it take a while for the vacuum to build up or something? Or is there something else I should be looking for?

Thanks, Bryan.

Sounds like they need to be bled. Or bleeded.

The Vaccum should build up pretty quick. The way to test the vaccum pump is, with the engine stopped, pump the pedal until it goes hard. Whidle holding the pedal down, start the engine. Within a few seconds the pedal should go down as the vacuum builds up. If the pedal doesn't go down, then chances are you've got a vacuum leak somewhere or the pump isn't working. It may be worth swapping the pump from the old engine.

My father's 1995 306 suffered from brakes that felt progreesively more and more "wooden" over time due to a worn through/perished vacuum line from the vacuum pump (gearbox end of rocker cover IIRC although it's been in different places on the various XUD incarnations I have worked on) to the brake servo. Easy to inspect and cheap to fix, I'd make sure both ends were secured nice and tight as well.

Warmest Regards Douglas
