Hi,

I had the front brakes changed on my 307 2.0 HDi 2 weeks ago. about a week later a message came up on the dash "brake fluid low". Brake fluid in the reservoir is fine. My mechanic said he did a two man bleed. Diagnostics return c1383 brake fluid level. short circuit to positive or negative .intermittent fault

This dash message normally only come on when you first start the car in the morning for the first 5 minutes you might get 2 or 3 notifications. After this it doesn't come on again for the rest of the day. The Abs light has also come on randomnly on three occasions but disappeared after a few minutes.

The car brakes fine

Any ideas would be greatly appreciated !
thanks

at that visit he changed the front track rods and the brake pads (both were advisories on last MOT). He's your average fitter mechanic, so diagnosing a problem maybe outside of his comfort zone :( He got his mate to get the code reading for me.

Would I be correct in assuming that the cause is likely to be one of two issues ?

1) air introduced into braking system/abs unit

or

2) faulty level sensor - I believe it is not available separately and comes attached to the brake master cylinder (http://www.peugeotforums.com/forums/307-38/abs-22407/)

any other possiblities ?

thanks in advance

is the fluid definitely topped up?

the sensor could be dodgy. i would think if its just reading the levels low it would be the sensor.
it needs a diagnostic check really

The fluid level light is exactly that, it only measures the level of fluid in the resevoir. It's just a simple float in the resevoir. When it's full the float pushes up and pushes the electrical contacts together to complete the cicuit which puts the light out. There's loads of s/h master cylinders on ebay, you don't need to change the whole cylinder, just the resevoir.

I removed the cap. Its filled to the top.

strangely it only comes on at the beginning of the days first trip every time you press the break pedal. Once the car has been running for a short while (5mins) it pretty much never comes up again for that particular day. Annoyingly, Problem then reoccurs next morning when I start the car and each press of the brake pedal for 5 minutes

is this not the picture of the level sensor ?

What would a diagnostic like PPlanet show ?

he said the work was done mostly from the underneath of the car and hence no need to disconnect the battery. He did replace the battery about 3 yrs ago, but he used a device to provide power to the car while the battery was disconnected.

The car doesn't seem to have the common symptoms of a BSI problem as windows, wipers, central locking etc work fine. Its just the issue of the brake fluid level warning every time I depress the break pedal. In the last few days its getting worse i.e. takes a longer initial drive before it clears for the day, about 20mins. If I tried a BSI reset could I potentially open up a can of worms ?

thanks
