gday guys ive just toped my brake fluid up about a week ago and double checked the lid. now the light has come back on...checked the brake fluid and yep its low again. wat would be causing this? and ive checked the master cylinder etc all works fine.


cheers jack

I some how dought that you are loosing brake OIL.

But you might be loosing brake fluid. Look along all your brake lines to see if there is a wet spot where it might be leaking.

sorry guts ment to say fluid. iva had a bit of a look after work but ill have to look again when its lighter.

Most common problem in the master cylinder leaks internally. Generally you can see brake fluid running down between the m/cylinder and the booster

If it's got drum rear brakes wheel cyl's are another very common thing to have stuff up so jack it up pull the drums of and look around if it looks all wet you prob should replace shoes as well. At the top of the backing plate there will be a round thing with 2 rubbers 1 at each end peel them back and if there stuffed brake fluid will run out watch your eye's i've had it come out under pressure and get on my face and close to eye's if that happens wash it out asap.

I take it you are not losing braking strength or getting a spongy pedal. If you are then I would look along the brake lines and calipers/drums.
I would also check the master cylinder, make sure you check inside the car as well, I have had a M/C leak inside once and run under the carpet so it took a while for me to find.

well i had a look in the morning and one of the front lines has split because they are to short for the lift i put in....never got around to getting new brakelines gone in this morning as i couldnt do it as i had to work. still not done so hopefully tomorrow morning so i cvan go camping at lunch.


cheers guys

My FJ62 was losing brake fluid and I couldn't find where the leak was. Got a new Master cyl as a precaution and found that it had been leaking into the booster, and still had an inch or so to reach the level of the vacuum hose grommet. Woulda had about 1 litre of brake fluid in there.

its all fixed now not loseing any now...tho not happy with some aspects of the work. i had to bleed the breaks again and clean the calipers and disk etc. i would of thought they would have done this
