hELP: Breakfluid burst ouT!

[Nodachi]

Hey guys urgent help needed, i've recently had my break change to DC2 from my stock EK.. reason for this is the break fluid burst once already.. this time it happened again, there has been small amount of fluid sipping out for the past few weeks and now it just burst.. fluids everywhere.. can someone give me any idea of where it might be the problem or hopefulli finds a solution? we had tighten the nipple and there is no visible fluids leaking from the oil line..
thanks

Can you find where abouts the break fluid is coming from ? Find that and then you can go from there? Try getting someone to use the break then watch it and that will usually make the fluid to come out of wherever the problem is.

sorry if im not much help :S

Where is the location of the burst? What did you replace when you put in DC2R brakes? Did you also change the master cylinder/booster?

[omgzilla]

I've seen a few brake fluid reservoirs burst off from master cylinders under high pressure. Usually caused by worn seats/locking ridges in the reservoir moulding or if you have too big of a booster on a small master cylinder.

As aaronng wrote - need more info: Is the leak coming from the booster, master cylinder, rubber brake lines? Have you put a bigger booster or master cylinder in? What did you replace/how did you fix the problem last time it occurred?

If you can't work out where the leak is coming from try wiping it all down and recheck it periodically and look for the drip marks.

Make sure that if you get any brake fluid on you paint wash it off immediately with lots of water, but gently flow it over the brake fluid spill - don't spray it with pressure or wipe it away.

okay i manage to take a look yesterday, the "oily" part is under the caliper, the nipple is clean, it is where the lower bolt to the caliper are.. i was told that the piston are screw... another thing i found is the cv joint is burst.. that might explain the fluid but doesn't explain the lossing brake fluid i had to refill it every now and den..

the last time the mechanic changed the whole braking ssytem, the disc, pads, and caliper sets.. last time both sides were burst together, now only one side..

again daniel ? same brakes ?!? Have you changed your brake proportioner yet ?

Changing calipers doesn't mean they reconditioned them. If they are second hand, there's a chance the piston bores are scratched. What you need is a new set of pistons, rubbers and a honing kit to lightly hone the bores.

Most likely you are best off taking it to a brake specialist, not a general garage to get it all checked and repaired.

To give you an idea, I'm currently replacing the cylinders on my EH's front drums and am just replacing the entire piston/cylinder unit with brand new ones rather than stuffing about. You of course have front/rear disks and the pistons are built into the calipers so it's more expensive.

When you changed systems over, did you check the proportioning valve etc?

[omgzilla]

Are you able to ascertain which part of the brake is leaking/busted?

The hose going to the caliper or the piston itself?

Has a larger booster been put on the vehicle and proportioning valve not been changed?

I would be taking the car to a brake specialist mate. If you're confident in repairing it yourself (which, no offense, sounds like you're not) then don't! Brakes are a big safety item - you don't want to put yours or your passengers lives at risk to save a few dollars.
