Brake Booster Or Master Cyl Leak?

[stÖrmy]

Hey guys i recently had an issue with my brakes. My standard handbrake is not bolted down so for about 2 - 3 weeks i had my hydraulic handbrake locked as the R32 was on a bit of a hill, Im assuming this caused the booster or cyl to die but im not sure. On the day i went to get the car tuned the brake master cyl was empty so i topped it up, The brakes worked but i had to push the pedal ALL the way down and there was no pressure, it felt like a clutch pedal.

I have removed the brake booster as shown in the pics below , i thought there might be a seal or boot or something that might have ripped under pressure but just by looking at the seals / boot they are not ripped or torn but as you can see from the pictures it is leaking somewhere, I assumed it was the boot behind the booster as when i pressed the brake pedal a few times i quickley ran to the front of the car and looked around the booster area and could see it leaking from behind but im still not 100% sure.

Any opinions ? Boosters are not cheap so i dont want to buy a new one unless i really have to but if i do then i will.

Mine did this the other week when I went to bleed them up (had front calipers off), I'm guessing it was a seal in the master cylinder and because the car has been sitting so long it ate through the seal on the booster as well. Picked up another master and booster from Steve May for cheap cheap

The booster could be fine. They seem to be a lot more reliable than masters. If its not leaking air it should be ok. I believe that masters should be rebuilt every 10years (or some similar interval).

Cost me $80 to replace both, it's was more annoying having to become a contortionist to get the 4 nuts off up under the dash.

80 bux ey, one bloke wants 4x that for both and another shop wants 100 just for the master. and yer, those bolts are f**ked, im a fatty and the only way i could get it off was to lie down upside down inside the car lol

You didn't say that you bled the brakes after topping up the m/c. If the level disappears than proper bleed is necessary. Booster contains only air and vacuum so if m/c is leaking no need to change booster.
