Default Brake fluid leak

Car is my cousin's 2000 3.0 and he has a brake leak coming from the driver's side front area. I haven't taken a look at it yet but will get over there tomorrow or wed. He almost ran a stop sign the other day. He doesn't keep up on maintenance on his car at all, has been without power steering for 2 years due to a leak in the rack he never got fixed. Going to try and fix the brakes, then the coolant leak, then the power steering for him over the next couple weeks, but like usually he doesn't have much money!

So for the brake leak I am going to assume it's either a hard line going to the caliper or the caliper itself, or the line connection to the caliper. So I will either have to replace a brake line or a caliper, my guess is the brake line, but this is without looking at anything. So if it is a line leak what is the best way to fix this? He said it was coming from the front left wheel so if the line needs replacing I would think it would just be the flex hose?

Any advice on what to check for or where to get parts will be much appreciated. Thanks.

i think the bigger concern is did he blow the booster or master. im guessing if the lines went dry he stepped on the pedal and it went to the floor. i had to replace a master due to this.

if the booster is bad the brake pedal will be super stiff. If the brake pedal goes to the floor, there's a fluid leak, either at the caliper, wheel cylinder or the master cylinder.

its possible to blow the booster or master when you pop a line. the rubber seal that are only used to getting moved about a half inch. when the pedal drops it moves more and blows the seals so just fixing the popped line may not resolve the total issue

If it truly is coming from the wheel well area then I would suspect flex hose or caliper. It should be pretty easy to spot once you get the tire off. By the sounds of it I wouldn't be surprised if the leak is just a small part of the problems you will discover. Please let us know what you find.

Thanks for all the advice everyone. I am going to look at it now and will see what the deal is. I asked him if the fluid ever went low in the master and he said no. But he doesn't have much mechanical experience/sense so I'm not taking his word for anything till I check things out. The car is in pretty rough shape, he doesn't do much of any maintenance on it, probably just oil changes so I'm sure I'll find all sorts of suprises when I start digging into it. Hopefully it won't be to bad.

Thanks again for the advice and will post back later today with more details.

Well I got over to my cousin's house today to take a look at things. Car is parked on gravel with many leak stains so couldn't tell much just from looking at ground. Took the front tire off since he said him and his dad thought that was where the leak was. All the front brake lines and caliper were dry and no signs of leak, besides power steering fluid running down the tie rod. He has had no power steering for a year or so now due to a leak!

So I followed the brake lines to the rear and under the driver's side rear door there was a pretty good leak. The metal lines rusted through and I could see it drip just sitting there. So it's going to need some line work.

The lines looked decent under the front door so can I just cut the line there and use a union to connect some new line after I get it all bent up? Also anyone know what size line it uses and type of flares, double or bubble flare?

Last, he said when the brakes went out the pedal went all the way down to the floor. Is there a way to tell if the booster or master is trashed now?

Thanks, I will start a new thread with what I found about the coolant leak.

i would replace all metal lines. they are cheap enough and if they are weak you dont want one to blow after doing all this work, the master and booster is another story. best way is to fix the lines and bleed it out and give it a try.

Ok I will get some line and some fittings and go to town.

Anyone know what size of line I need? And also is it a double flare fitting?

Thanks
