Rock hard break pedal

[owly]

What would cause this. When i put my foot on the pedal its rock hard car will stop slowly.

Is it the master cylinder that would cause this?

A spit in your vacuum hose or failed vacuum pump would cause rock hard pedal

So i shouldn't go near the master cylinder. I dont think any of the pipes are damaged is there anyway or testing the vacuum pump

[E46Padge]

Pop the pipe off the brake servo give it a couple of revs and see if you have vacuum

im hopeing its not the servo because it looks like a right pain replacing that

[E46Padge]

It's a nasty job. Post up your findings.

Took pipe off to check the vacuum and its perfect.

Going to double check all the piping for tiny holes but 99% sure at this stage its not this.

Whats my next move anyone

Beer bottle under your brake pedal? Only messing.
Did this happen suddenly or gradually over time? Petrol or diesel, don't diesels have vacuum pumps?

Got sorted lads its a 318tds engine in a 318is coupe shell.

Brought a new hose from the vacuum pump to the servo and works a1 now. Delighted i didnt have to do to much ripping.
