It usually is not necessary to relace e line all the way back to the master cylinder. There is usually someplace along the line that can be flared and a barrel connector used to add new line. If you really want to replace it al the way to the master than it would be a good idea to bring the fittings with you when you go to pick up the new parts. This way there will be no communication issue between you and the parts people and you can make sure you are getting the correct parts before you leave the store. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

    I work in MN, I know all about rusted brake lines.

    As far as the master cylinder it is pretty common for them to fail after there is a rupture in a brake line or hose. What happens is years of debris will settle in the end of the bore that the pistons and seals never reach when the brakes are working properly. When there is a failure the piston and seals travel into that area, run through the debris, an ruin the seals. This can also happen when bleeding the brakes if your not careful.

SOURCE: How do you replace brakes on 1999 Pontiac Sunfire?

The engine size don't matter except when you order the parts. First you will want to chock the rear tires. This is a front wheel drive, when you jack the front, park wont work. you should also set the parking brake.
You will want a metric socket set and rachet, and a fairly large flat head screw driver.
Remove the wheel.
When you look at the brakes, you should see 2 bolts holding them on, If they have a star shape that looks like a screw driver might fit in it, it is a torx bit, you will need to replace the wheel and go get one. The guy at the parts store should be able to tell you what size.
I'm pretty sure it is going to be a regular hex nut, probably 12 or 13mm.
You can loosen them, but don't remove them yet.

First you need to depress your caliper. This can be done a couple ways.
I just insert a screw driver between the pad and the rotor(the shiny thing that the pads make contact with.) Carefully pry the inner pad slowly away from the rotor. Don't scratch the rotor, you can dig into the pad all you want, your putting new ones on.
Once the inner pad is all the way in, then you can remove the bolts and the caliper will slide out.
Remove the old pads and replace with the new.
Put the caliper back on, make sure you get the bolts tight.
Do the other wheel the same way.
The other way to get the caliper pushed in, by the way.
Remove the bolts, remove the caliper from the rotor, Use a large "c" clamp to depress the cylinder.

P.S. Do not under any circumstances remove your brake lines.

When you are finished with brakes and have tires replaced....

Caution!!! Before you start your car, pump your brakes a few times. Check your brake fluid. You more than likely wont need any, but you should always check it.
Also, do not add brake fluid before replacing pads, the level is going to be higher with new pads.

Back brakes will be similar if it is disc, if it is drum, do your self a favor and have some one else do it or get a service manual. I could walk you thru it, but you need more tools and you have to adjust them....
Better to pay $100 or so and have it done right.

I have 1988 cadillac allante the lh rear brake line rusted through know the brakes wont bleed no mater what i do even tried staring at abs pump and master evev replace some calipers

You may need to go to the master cylinder and release the piston for the rear brakes circuit. It is best to get a manual for this operation as it may require the removal of a switch in the master cylinder or a threaded pin between the pistons. There are two pistons that are spring actuated and when one circuit loose pressure a piston is stuck in the wrong position.

Can i replace slave cylinder without removing transmission

Yes, follow the brake fluid line from the clutch master, you'll see the slave, two bolts and a brake line, very simple. Bench bleeding before you install new one will save time.

My 1999 pontiac keeps breaking the clutch master cylinder it wont keep the pressure. as soon as u hit the clutch u hear a pierce noise and open it up. and the mastercylinder is destroyed

try replacing both master and slave cylinders at the same time. when both are removed apply brake cleaner and shop air to high pressure line running between master and slave cylinders to clear any possible cloggs. If it happens again remove your transmission and inspect clutch, bearing and linkage in bell housing for broken/binding parts.

Rear brakes lock up very easy

leaking brake fluid or lining dust causes locking. take drums off and check brake cylinders for leakage at rubber boots. If leaking, replace cylinders and clean shoes with brake cleaner. If no leakage, clean out all dust with brake cleaner. Adjust shoes up tight to drum and reinstall. Let me know if you have questions or need instructions.

1999 sunfire replaced left rear brake line now i can not get fluid to rear brake lines

There is probably an air bubble in there.
Get a partner to push on the pedal as you simultaneously open up the bleeder screw.

One shouldn't have to use the abs brake bleeding procedure if no air got into the abs braking master cylinder area.

Keep trying to manually bleed the air out of the brake line. May have to tilt the car backwards to get the fluid to drip out by itself,
although air in the line can sometimes be difficult to get out after changing the rear brake line.

Good luck on this repair.

Cant bleed back brakes

Make sure the reservoir has fluid. A 1/4" drive ratchet and correct metric socket work good on the bleeder. When bleeding, never press the peddle more than 1/2 way down. When you go all the way down the master cylinder seals travel into territory with tarnish buildup. If you do/have you will probably be needing a master cylinder soon. Antilock brakes complicate bleeding sometimes. Just filling the reservoir and letting it set with the bleeder open allows the fluid to gravity down. Also, screw the bleeder clear out, maybe the hole in it is plugged.
