My 2001 mercury grand marquis, when stopping at a light breaks went to the floor and the car accelerated which cause an accident.why are these cars loosing breaks and accelerating?

You have not shared what art of the country you live in, but I may be able to guess your answer.
All cars as old as yours are subject to brake failure, usually from leaking or rusted components.
A good inspection now should show you the rear brakes are bad, and perhaps the brake lines have rusted through.
Could also be a rear brake cylinder has failed, leaking out your brake fluid, and causing the brakes to give out when you needed them most.
Routine inspection probably would not have caught that, but having your brakes serviced every 7 - 10 years should have prevented it.
Lots of people do not do a complete brake service because it can get really expensive, though it would prevent your accident.
The acceleration problem is a whole different matter.
God bless your efforts.

How and why has my front subframe corroded on my 2006 corsa

subframes are made of steel and that makes it subject to rust from salt on the roads in winter. Leaking batteries also corrode the steel. brake fluid ;leaking will also cause rust in steel. so bad that it failed and inspection then the answer is to get a subframe from the wreckers ( good frame not rusted or bent) and have it fitted to the vehicle.

Brake fluding leaking on rear passenger

Most brake fluid leaks, especially from vehicles of this age are caused from rusted through lines. Take a look under the car and look at the line on the axle, you will likely find a wet spot. If you can't locate the leak easily, fill the brake reservior and have someone pump the brakes to find the source. Another common source of leaks are wheel cylinders. If this is the case you will notice brake fluid on the bottom of the drum backing plate. You can remove the brake drums to confirm this.

Steel brake line going to the brake brakes is leaking up under the frame is there a joint there ? what kind of brake line is that and joint fitting ?

Often when I see a brake fluid leak in this area it's due to a brake line that has rusted through due to corrosion caused by road salt, water, dirt, etc. I'm not sure if there's a splice in that area but I don't believe there is. Because this is potentially a very big safety issue I would have a service facility do the repairs on this one. Hope this helps a bit and good luck!

I'm leaking brake fluid in my the rear my truck

Hello rodeure
The brake fluid can leak from a few places in the rear. Bad wheel cylinder/brake hose or the most likely cause, a rusted brake line.
Fill the master cylinder and have somone step on the brake while you
look under the truck. When you find the leak, the best thing to do is to
replace the lines up to the front valve (they don't rot in one spot) then
bleed the brakes and you should be good to go. Hope this helps.

1999 daewoo matiz has lost brakes fluid has leaked out. what is the most likely cause?

You must look for 'wet' areas under the car to determine where a brake line may be leaking fluid. This can be caused by corrosion (metal brake lines rusting away), or damage, if the car ran over some debris in the road. The front brakes have flexible rubber lines attached at the wheels, so the car can turn, and the lines 'flex' or move. The rubber can deteriorate over time, causing cracks that can leak fluid. So, you must be a detective and examine the underside of the car to determine where the leak is. If you can't find any evidence, the last thing to check is the master brake cylinder, mounted on the firewall. If the seals go bad, you should notice leakage, usually only visible inside the car, under the dash where the brake pedal meets the master cylinder.

Back right brake caliper leaking brake fluid

Sounds like the brake line is just rusted, you'll probably have to change the brake line and then bleed the brakes

If you had a brake job you might have air in the system that needs bleed out.
Crack open the bleeder on the caliper and watch the brake fuild come out steadly and close it and don't pump the pedal. Do this to each side this is called bench bleeding and watch the brake fulid level while you are doing this add fuild as you bleed each side.

Also sounds like a leaking line check under the car for a leaking brake line. Next would be a master cylinder problem. But more than likely a brake line might be rusted up and leaking, sooner or later you will not be able to stop. If its a leaking line it will leak all the fuild out of the master cylinder. You can replace the line and use the bleeding procedure in step one.

Brake line leak, between frame and fuel tank

You should be able to re-route a new section of line w/out any trouble. If the line is leaking due to rust, you might want to replace all the lines at once, since the rest of the system is probably rusting away also. If you plan on keeping the truck for a while, all the more reason to replace it all. I must add, I hate those rusting brake lines! Did mine over 2 times on y 90 F-250, salt and snow plowing do a number on them.
