307sw 136 hdi brake servo failure

Post by Peter.N. »

Hi folks

I am staying in Sevenoaks with a friend until tomorrow and he has a brake problem with his 307, when cold the servo sometimes doesn't work until it gets warm. Any suggestions?

No common problems as such, but it depends on what you mean by warm.
If it works after about 30 seconds of engine running, I guess it has a leak, in the vac system, most probably the servo its self.

It only happens in very cold weather, it will clear after several operations of the brake pedal or if you leave the engine running for about five minutes but it is apparently getting worse i.e. it happens when its not so cold, doesn't happen in normal driving though, only when you first start.

As others have said probably vac leak. Could be vac pump itself failing too.
