Is it safe to drive with a leaking brake cylinder?
No
Is it a leak in your brake line if your brake light came on and went off after it was topped off then happened again a few days later and how much to fix?
It is either a brake line or the master cylinder or a wheel cylinder/caliper. Park on a clean dry surface. Look under the car for wet patches on the ground, especially behind the wheels, it may indicate where the fault is. If the surface remains dry then it is likely to be the master cylinder/servo. It is difficult to say what the cost will be because of the disparate cost of the individual parts. Having said that, the repair could be around $300. But you must get it seen to straight away, it is not safe to drive.
Why does Brake pedal keep going down?
Sounds like u need a new master cylinder, dont mess around with breaks, its better to be safe then sorry. When a master cylinder wears out it no longer holds the pressure and will cause the pedal to go to the floor. Also check your brake fluid level, if it is going down u may have a leak. Have your breaks looked at asap.
Is it safe to drive when there is a leak in the vacuum of the brake servo?
Generally no
Is it safe to drive a car with a rear cylinder leak?
No. Get it fixed as soon as possible. When you have brake fluid leaking out of your rear cylinder, you are putting lubricant on your rear brake. That is keeping that brake from working. It is also letting brake fluid drain out of the car. Your car needs brake fluid to stop the car. If you lose a lot of brake fluid, you will put your foot on the brake pedal and it will go all the way to the floor and nothing will happen. It can be dangerous when you drive down the highway at a high rate of speed and put your foot on the brake pedal and nothing happens. When you crash your car and turn it into a piece of scrap metal, you could get hurt.
What would cause the brake pedal to go all the way to the floor on a 1995 400 Lexus sl?
No fluid or the master cylinder is shot or a wheel cylinder/caliper/brake pipe has failed. Check the fluid level first. Check the driver's carpet and the brake pedal for wetness (master cylinder). Move the car slightly if safe to do so and see if there is a light watery oil where the wheels were, or get underneath and check the calipers/hubs and flexi-hoses for wetness. Next, run your hand along the metal pipes and check for wetness. If there is wetness chase it to the source and replace the failed part. If there is no wetness anywhere it is likely to be the master cylinder that has failed. Unless you are very experienced get the brakes fixed by a garage; lives are at stake.
Is it safe to drive with a bad brake booster?
No it's not safe. In an emergency situation you may not have ample stopping power.
After you replace a brake master cylinder and bench bleed it do you still need to bleed the entire system?
YES!!! It is very important to ALWAYS bleed the entire brake system anytime ANY component is removed because air will be allowed into the system. Air in the system will cause poor brake performance and or failure. Start bleeding at the wheel farther-est away from the master cylinder and work toward the master cylinder. Usually in this order...RIGHT REAR/LEFT REAR/RIGHT FRONT/LEFT FRONT. Do not worry if no air comes out from some of the bleed screws but be sure to bleed each wheel until fresh fluid flows out. Keep a constant check on the fluid level in the master cylinder while bleeding the lines. DO NOT LET THE MASTER CYLINDER RUN OUT OF FLUID!!!! If the master cylinder runs out of fluid it will allow more air into the system and you will have to start all over. Follow these guidelines and you should have SAFE Brakes with a good pedal feel. One other note: Most Brake Fluid will damage Automotive Paint. Have a bucket of soapy water nearby and if the Paint is touched with Brake Fluid from your fingertips or any other other source stop work,wipe off the Fluid, and wash the area with soap water. It only takes a minute or so for Brake Fluid to damage paint.
How do you troubleshoot disk brake problems and diagnose and fix common brake problems?
I diagnose the brake system starting with inspecting the master cylinder and the level of brake fluid in the reservoir, then if safe to do so, a road test, then I remove all four wheels, calipers, drums, brake pads, measure the rotors/brake drums and do an inspection of each brake assembly on each wheel including the brake lines and brake hoses. Then make a list of parts needed to bring the brakes up to specs.
Is it safe to drive a car when one cylinder is misfiring?
It depends on the reason that cylinder is misfiring. It could cause serious damage to the catalytic converter.
How safe is it to drive a 4 cylinder car across the desert?
If it has been well maintained, no problem.
Is it dangerous to drive a car with no brake pads?
well if someone told you that it is ok they are partely correct no your not realy safe driving around with no brake pads it reduces the cars ability to come to a stop in time of a needed reaction but lets say you know the car needs the pads and you can drive it to the nearest brake shop go ahead just go a tad slower and be a more precatuios driver.but techanicly no it is not safe to drive without brake pads.
