If you wish to do that as a maintenance procedure, just use a turkey baster and replace the brake fluid in the master cylinder reservoir once every six months. That is sufficient to remove enough fluid that has drawn in moisture and will dilute the fluid remaining in the system keeping it in good condition.
If you are working with a severely contaminated system, there is a bleed valve on each caliper or wheel cylinder (it looks like a grease fitting). Have someone lightly depress the brake pedal and then open the bleed valve. Before they release the pedal, close the valve. Do that at each wheel, beginning at the passenger side rear, driver side rear, passenger side front and ending at the driver front. Frequently check the level in the master cylinder to prevent it from running dry.

There is a drain plug on the brakes. You have to remove the drain plug and pump the brakes until clean fluid comes out, each wheel at a time. I would let a brake place do it. They have the tool to put clean fluid in and you don't need anyone to pump the brakes.

1 How does one remove the right cv axle. 2 Our garages does not sell dot 3 break fluid anymore. Can i use dot 4 break fluid and must the system be flushed before changing to dot4???


Systems designed for a particular type of fluid ( especially prior to the wide distribution and use of DIT 4 fluids ) should continue to be filled with that fluid
for example in a car that was delivered with DOT 3 fluid , the internal components of the system ( seals , brake hoses, and fitting for example ) were specifically designed and tested for compatibility with the chemical composition of DOT 3 fluid
Because DOT 4 fluid typically contains a different chemical composition, compatibility of system components may be an issue
-- extract from stopcheck--high performance brake systems--
another site that has an explanation of the DOT ratings for brake fluids is www.tccoa.com>brake fluid
Basically DOT 4 will replace DOT 3
it is more expensive and good practice will require the complete flushing of the system
THE ONLY BRAKE FLUID THAT CANNOT BE USED IS DOT 5 AS IT IS NOT COMPATIBLE WITH THE RUBBERS AND SYSTEM
I suggest that you read the tccoa site as it has a good explanation and offers a clear understanding of the DOT system
Lastly ,if you still have doubts the shop you should be talking to is an accredited brake specialist shop , not your local mechanic that has a limited knowledge of and relies on the sales pitch of the fluid manufacturer

Brake System Flush and Power Steering System Flush


I doubt Nissan has a set recommendation for either one.
Generally both systems are sealed and the fluid should last for the life of the car. You could flush each system every 50k if you think there is a chance they could become contaminated.

1996 toyota celica st202 abs light come on intermitently


While it may be an eletrical issue developing, it may also be internal to the hydraulics of the brake system. If the system was recently flushed, I would look at the wheel sensors first- make sure thery have not picked up debris and sensors are snugly mounted and wiring in good shape.

If the brake system has not been flushed with new fluid, the system should get flushed out next time brakes are serviced. This may mean an expensive repair, but it depands on how comfortable and experienced you are without ABS at all.

If the ABS fails- all that happens is you lose the brake pressure modulation. Fancy word for braking yes- pulsing of the pedal by the system- no. The wheels or a single wheel "might" lock up while hard braking possibly changing handling dynamics of the vehicle..

Problem with brake system on 2002 dodge dakota brakes replaced, new rear drums, brake fluid drained, flushed and replaced, wheel cylinders replaced, brakes adjusted, no leaks at master cyclinder. Brakes...


A 2002 should not need a new master cylinder yet. If it is the rears grabbing, they probably installed something wrong, or they did not get all of the air out of the system which would be my best guess. A professional brake flushing machine is suppose to replace the old brake fluid with new while not letting air in. But tiny air bubble can form, and 3 days is just enough time for them to gather into larger air pockets, causing problems. Tell them you want all 4 corners manually bled before they start replacing any more parts, a step they should have done in the first place. If it is just the front brakes grabbing, the flush may have knocked dirt loose, messing with the front calipers. Either way, they will have to bleed the brakes after replacing them, at a cost to you and blame it on faulty parts. Long story short, I believe they cut corners when they flushed your truck, and are now looking for a way to blame it on parts.

What is the order to bleed the brakes?


Step by Step:
Make sure the person in the drivers seat applies adequate pressure, when another person opens the bleed valve.
Step 1: First make sure you have plenty of brake fluid and do not run out.
Step 2: Start by bleeding the Right Rear.
Step 3: Then Bleed the Left Rear.
Step 4: Right Front
Step 5: Left Front is last.
Make Sure all air has been released do not move to the next wheel until all air is out of that wheel. When done make sure Brake fluid is full. Then test pedal position. Recommend bleeding with vehicle not running.

My ex wife put power steering fluid in the brake master cylinder and drove the car across town..... what should i do


Immediately **** out the contents of the master cylinder, replace with fresh brake fluid, and flush the system.

Flushing can be done by doing a good old fashioned manual bleeding consisting of one person opening and closing the bleeder screws and one person working the brake pedal or many shops will have a brake flush machine that will make quick work of the job.

The P/S fluid in the brake system will cause the seal to bloat and eventually fail. We see several cars every year that this happens to. If its caught early a system flush will take care of it. If ignored everything gets replaced (master cylinder, brake hoses, calipers, and wheel cylinder). We have had a few over the years that where ignored for so long that the brakes eventually locked up.

I need to know what should I take care of 1st with my car. It needs the following; rear shocks battery hold down tran fluid flush brake flush cap rotoe wire need replacement feul systme flush drive blets...


Sounds like you have been talking to a very aggressive sales person!! Assuming the car is running halfway ok, & without seeing the condition of anything the most critical in terms of breakdown are:

  • belts
  • brakes
  • battery hold down
  • cap, rotor, wires, spark plug
  • trans, brake & fuel flush(by the way..no where in your maintenance manual does your car call for flushes of any kind!!) Go by what it says in your book

Brake Problem


It looks like one of your break lines have gone bad and needs to be replaced. It's more common for the one of the front brake lines to have gone bad, replace both sides, flush out the brake fluid and bleed the system to ensure there is no air in the lines. You can go to Auto Zone to buy the new brake lines and they will also have the step by step instructions for you the get the job done. Note: locate where the leak is coming from to ensure that it's not a bad brake Cylinder at the rear brakes, of one of the front brake caliper's, or the master cylinder. Regardless Auto will have all the parts and step by step instructions so you can get the job done with common tools. Good luck and keep me posted, be glad to answer any questions you may have.
