Brake Problems

[kbekl]

right i have a 1996 2.0 galaxy that is giving me some problems with the brakes :lol:

 

i was out for a full day and covered nearly 300 miles with the brakes fine (did go down a really bumpy dirt road)

 

the day after i went to go to the shops and on pulling out of the drive put the brakes on and the pedal went straight to the floor with next to no braking at all also had a hand brake light up on the dash which i guessed was the fluid level

 

i toped upo but the brakes have still not been the same with and i have topped up the system again with no change in the result

 

i dont seem to have any fluid on the drive or road that i can see, also if the car is not running i the brakes dont go to the floor but takes a couple of pumps befor it is back to normal, if i start the engine with the pedal pushed in then the pedal drops slightly but then upon releasing then it goes to the floor again i can pump the brakes a couple of times to make it better but on release it is back to normal

 

the hand brake seems to be fine so i guess i have shoes a the rear not powered by the fluid

 

any ideas what too look at

Hi there You said you topped up the fluid? was it actually empty which I suspect it was you need to check very carefully around wheel units and brake pipes, do you know if you got ABS or the old conventional vacuum servo if you still cant see any visible leak and you have the latter your master cylinder could be leaking back into your servo.

All Galaxy's have disc brakes front and rear you need to check all four wheels, that fluid is leaking somewhere and you need to find it dont just keep topping it up!! :16:

Had a similar - and frightening - experience on my Alhambra.

Finally tracked it down to a leaking brake pipe at the back of the car next to the spring for the handbrake cable.

The fluid would only seep through when the pedal was pressed and so two people were needed to find the fault.

As chrispb123456 has said, something is leaking somewhere and I would get it checked out pronto for safety's sake!

finally got round to checking the calipers and their is fluid on the rear caliper and the axel so it seems that thier is a leak their

 

but on testing the brakes with a person in the car pumping the pedal their is no visable fluid loss

 

are all the rear calipers on the galaxy/sharan the same though out the years or do they change

Hi galaxy/sharan are the same for your year so any rear caliper petrol or diesel long as its mk 1. 94-00

It wont leak while there is pressure as the pressure with make the seal work better, while its at rest it will seep past, did it get so low you have air in the system?

i think it did as it just went over night back area is covered in fluid so while the hand brake is on the fluid id seeping past the seal ?

 

when i went to top the brakes up the first time when it went straight to the floor took about 500ml to fill it to max

Hi you need to change the leaking caliper then bleed ALL the brakes
