Metal brake lines rust with age, become potted & leak fluid. Replace with copper pipe, is only marginally more expensive, the labour to replace will be the same but copper wont rust, so future cost saving & safety. Job is easy enough to do yourself, unscrew where it joins master cylinder, then follow line back, clipping it out from any securing clips, unscrew other end, coil up & take to motorfactors, ask them to make a copper brakepipe exactly like your old one, dont worry if you snap pipe during removal, take all bits with you so correct length can be gauged. Copper is very flexible & can be bent to shape when you refit. Make sure you have new brake fluid to bleed your system with after replacement.
Have fun.

You did not say if a break line is leaking, i'am gussing one or more are, if thats the case, there is no sequence on changing them,just they have to be bleed when you do change one or more of them to get the air out of the system, they will usely spring a leak wearever there is a clamp that holds them in place. There are one line to each wheel and a main line that runs from the front to the rear, there are differant costs to this depending on how many lines are leaking and if you do it yourself or have it hired done.

My park brake light will not go off


assuming your parking brake is fully released, you may want to check and see if you are low on brake fluid, as this illuminates the red brake lamp also. Normal brake wear cam reduce the amount of fluid in the master cylinder, but have the system checked if this is the case.

first check on every wheel make sure you see no wet . from brake cyclinders leaking. make sure brake fluid is full. when you replaced master cyc. did you bleed that before you hooked lines to it if not do that. abd bleed all brakes again. if still pedal goes down then it is the brake booster its self. hope this helps.

1994 Cadillac Deville has been sitting in a garge for ten. What will I need to look out for when first starting after ten years


Replace all fluids (including fuel) - coolant (may want to flush system), engine oil, drain and replace transmission fluid and filter, drain and replace rear end fluid. Also change fuel and oil filters. (may be a filter at the end of the fuel line going into the carburetor as well0 If fuel was left in the system - it may have evaporated and clogged things like your carburetor jets. There may be gum (varnish) in your carburetor float bowls. Hopefully your valve seals are not dried out (oil will leak into the cylinders if they are cracked) - or any other rubber parts for that matter (hoses- rda - heater - power steering). Your brake fluid absorbs water over time and with need to be drained and replaced - bleed all lines. Be sure that all lines are not rusted and that your master cylinder and brake cylinders function. Lots of thing =s to check - I hope I covered most, if not all. Let me know how you make out getting it going. Thanks. Good Luck :) !

Replacing brake fluid


Brake fluid absorbs moisture, and this can rust the insides of the brake system. The moisture was not that big of deal 10 years ago, but on ABS brake systems of today, the rust and other debris that accumulates in the fluid can do lots of internal damage, and can be very costly. Brake fluid can also break down over time from excess heat that is created from within the brake system.
It is recommend flushing the brake fluid system about every 30,000 miles, or at 30K, 60K and 90k tune up. It cost about $90, but you can do it by yourself. To do this flush, open the brake lines located at each wheel and allow the brake fluid from the brake master cylinder to "bleed by gravity", as continue to feed new fluid to the master cylinder until the fluid runs clear at all wheels.You need two people do do this job. One at master cylinder brake fluid bottle under hood, adding fluid, and the other one under the car tightening up the bleeding nipples as necessary, until the discharge clears up. The discharge has to be collected in 16OZ plastic bottle via clear vinyl hoses from the bleeding nipple to the bottle. It is a good idea to replace all 4 nipples with new one. They are cheap and avoid problems in long run. Make sure to use at least DOT 4 brake fluid. Make sure to use a sealed bottle. The life of brake fluid in an open bottle is one week. If the brake pedal is spongy, then go for bleeding of the brake system, one wheel at a time. You must inspect all breaking system components, from master cylinder, up to calipers, or rear brake cylinder for any leak, or malfunction. check the status of brake lines for rust, and if necessary replace or undercoat them.

Servicebreakfluidswitch warning light comes on what is it and where is it how do you fix it. 1999 cadillac deville


I think that there is a fluid level switch on the master cylinder or in the reservoir. Check to see if the connector is ok. And, also, check to see if the brake fluid level is up.

Brake pedal goes all the to the floor. can not


Check the reservoir to be sure the fluid is full. If not, top it off and try it again. If there's still trouble building pressure, pump the brakes a bunch of times, and then check around each wheel for fluid on the ground. If you see none, it's possible that you have a break in the line somewhere through the chassis and that the fluid is leaking out inside. If you see no evidence of leakage, and the reservoir is still full, you need a new brake master cylinder - what will have happened is that the diaphragm around the plunger inside the master cylinder (which moves through the cylinder when you push the pedal, and forces fluid out to the wheels) has a hole or tear in it, so instead of pushing the fluid out to the brakes, the plunger simply moves through the fluid. It never builds pressure, and your brakes don't work.

Oil missing out of master cylinder oil on rear line going to back brake


You have a raptured brake line. Mostly from rust. Everytime you apply pressure to the brake pedal that is why its taking brake fluid. Keep adding brake fluid to your master cylinder-don't let it go dry or you will lose all of your back brakes if you didn't already. You have to have your brake lines replaced and have your brakes bled. Should be about a $100 job at a good brake shop.

Replace brakes. now they go to the floor. bled air


When you fixed the brakes, did you take the lid off the master cylinder. I just wonder if you spilled out your brake fluid. The only reason the pedal should go to the floor is if the brake fluid is gone or the master cylinder is not working. Check the fuse. Check the brake fluid level. The pedal only goes to the floor if there is no back pressure in the lines between the master cylinder the lines to the brake pistion on the calipers. Please give me a good ratin and keep me informed.

if you can see a good amount of wet brake fluid between the brake master cylinder and the brake booster. and you have been adding fliud often,you could have a bad master cylinder. it has to be replaced not rebuilt. you however may have a far more common problem, a rusted through brake line.have someone pump the brake pedal, than look under the car for a brake fluid leak ,repair as needed. than bleed the brakes for a good hard brake pedal
good luck chris
