Hard Brake Pedal

Hi,

I was driving to work last week and I was coming to a stop behind a car at traffic lights, luckily I wasn't tailgating and left plenty of room, as my brake pedal went hard and I really hard to put all my weight in the the pedal to stop from crashing into the car in front.

So, as i was in the countryside and I knew there was a layby about 100 metres ahead I pulled over using engine braking and handbrake. I turned off the engine, did some googling and when I tried the brakes again they were back to normal. Luckily I was right by work and knew there was a car garage nearby so I dropped it off (it was in the same garage day before for an oil change).

Since then they have worked fine and the mechanics couldn't find anything wrong.

I have had the car for 15 years now and it's just hit 250,000 miles and it's never happened before.

What do you suspect had happened and needs further investigation?

Many thanks

Vac leak .

Gaz, is it the vacuum pump? Just searching online and want to make sure I am looking at the right part. I'm guessing because it's happened once, it's likely to be a risk from now on.

What engine code Al ?

Sorry haven't forgotten about this thread. Christmas and new years got in the way. Hopefully get a chance to check this weekend. Car has been fine since by the way.
Very strange, but in a way it would be nice to know what it was or is, so I can prevent it again.

Hi Gaz, where abouts will I see the tandem pump?

I think I may have found it. It has the words 'vapec 14s' written on and a sticker which says '7.24808.0' and after the '0' the numbers aren't visible. Can't see any part number.
