Question about 1997 Oldsmobile Eighty Eight

2 Answers

Having problems with my brakes on a 1997 Oldsmobile 88. Looks like a steel brake line is rusted out between the front and rear tires. That's where the leak seems to be coming from. Any ideas on how much something like that would cost to repair or if it's something I could possibly do myself? I've changed the brake pads on my car before as well as other minor issues but nothing to do with changing lines. Any help is appreciated.

0. jack up the car, get tool. yada yada

1. Make sure you have isolated the leak - in this case it seems to be between proportioning valve and the brake hose.

2. remove old line. its easier to cut near the ends and put a socket on the hex nut.

3. dont throw it out! use it as template. dont lose the brackets and clips.

4a. buy 3/16 steel or steel with PVC coating (comes in 25ft coils on ebay), you also need flare fastner and flare tool. Cut to length with pipe cutter, clean ends with a file, put on two flare fastners that are identical to the old ones and use flare tool to make double flare on each end.

4b. go to dealer or auto shop and ask them to do it.

5. spray the line with rust protestant then bend and re-attach the steel line.

6. bleed the brakes - the reservoir should still have fluid for the front, so you only need to bleed both rear sides.

TIPS:
- its a good time to replace ALL brake fluid. Dont use any old bottles!!
- NEVER let reservoir go below half full or else you might need to re-bleed all over.
- attach a plastic tube to the bleeder bolt. Submerged other end in bottle with some brake fluid. This will prevent air from being sucked back in when your assistant pumps the pedal.
- initially, you can use air compressor, or "blower" on your shop vac to push air and thus brake fluid in reservoir. Once you have it setup with an air tight seal, go and open each bleeder screw until STEADY stream of fluid comes out. Dont forget to refill reservoir!

Very cheep fix. First remove the old leaky line and determine how much line you will need. The line is usually sold unbent. You will have to bend the line. I usually lay the old line right beside the new so i have a refference of where i need to make the bends. You probably wont need a bender, most cars come with 3/16 brake line and you can bend that by hand. You will however need a speical tool to cut the correct length. Just take the old one with you when you when you get ready to buy new line. They will get you everything you need. Should be around 50 bucks to fix it yourself. You will have to bleed the brakes after you install the new line though. Good Luck

SOURCE: Rear brake lines rusted through?

From the information you've provided, YES, you seem to be getting ripped off. This does not sound like a scrupulous mechanic. I don't know what recourse options you have available to you against this shop, but you need to go somewhere else.

SOURCE: Ruptured brake line

unless modifications were made to the factory settings then you can go to any parts store ad buy a brake line. there is a hard metal line that runs from the master cylinder to the back of the car and then there is a rubber hose that connects the hardline to the brake system. that is all you will have to replace.

remove the tire and check and see, you may be able to see it by jacking up the car and crawling under it. all you need is a wrench and a new hose, you will have to bleed your brakes after replacing the hose.

I have a 1997 chevy blazer that has a brake fluid leak just underneath passenger rear seat on drivers side and cannot find how to see what the heck is leaking what is the best procedure to figure out what...


you most likely have a brake line rusted threw, cut the line ahead of the leak and after the leak and splice in a new piece of brake line, it will have to be steel, you can not use rubber. if you take the line to a parts store they can size it up and get you a piece of steel line and some pressure fittings to put it back together, after you repair the line then you will need to bleed the rear brakes.
