Audi a3 break failure

Hi, i had total brake failure and found a leak where hose goes in from the top and meets caliper. I fixed the leak and went through the bleeding proceedure, i got fair pressure on pedal and kept topping the fluid up. All wheels done so i went to test brakes, my foot went to the floor and brakes did not work. We had to top up nearly a bottle full and lost the fluid. No sign of any leaks, is this a master cylinder failure????

SOURCE: can't bleed coolant system on Audi A3!

In my experience with Audis, after any job requiring changing/draining the coolant the car ideally needs to be driven. With the coolant topped up to max drive the car, keep the revs up and shake the car with steering and over bumps where possible. Whatever you do make sure you take at least 2 litres of water/coolant with you, as as soon as the air lock goes, the level drops a lot and quickly. Also keep an eye on the temp gauge and avoid letting it go much over 90 degrees (over 90 on the gauge usually means its well into the hundreds) When you get consistant hot air through the heater, at idle, the level should of settled. If this doesnt work you may have thermostat issues or a blockage. Good luck, let me know how you get on.

SOURCE: how do you remove the rear brake caliper on a Audi

If Theyre Lucas brakes there is located on the back side of the caliper two hex bolts I think 10 or 12 mm.
You have to remove these screws and pull the bolts out.
Should be one on top and one on bottom.
They might have a rubber plug that covers the hex indention in the screw.
Theyre located by the accordion looking rubber boots behind the calipers

For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!!

Brakes keep locking up on 1999 f250


Sounds to me like you could have some brake hose problems. When you apply the brakes the fluid leaks inside the hose and locks the calipers. After it set awhile it bleeds of itself. That is also the case when you open a bleeder.

It could be one hose or all of them. Most likely one of the main hoses.

E2000 mazda tray top .weak fluid pressure from master ,fcylinder to caliper foot pedal does not pump up pressure enough to bleed caliper


Yes it could be a bad master cylinder. But always remember when bleeding brakes. No matter what component on the brake system was changed. You ALWAYS bleed all four wheels and rule #2 ALWAYS bleed from furthest from the master cylinder first and work your way to the master cylinder. This ensures you remove all the air from the break system and not just move the air back and forth inside the lines. Try that. Hope this helps.

How to replace front break pads


Ford Taurus - Front Brake Replacement A couple of things should be noted before you begin. Number one is, don’t be alone when you do this. If the car is in the air and it falls on you, all of your money saving ideas go out the window because you are dead or really hurt. Seriously, if you are going to work under your car while it is up on jack stands (not a couple of tree stumps or your child’s Hot Wheel or the two big rocks you found in the garden) let someone know so they can check on you once in a while. Another thing, the brake pads and linings may contain asbestos so don’t inhale the brake dust or blow it out with compressed air. Never use petroleum based solvents to clean brake parts and make sure you use a DOT 3 brake fluid when filling the master cylinder. 00:35 Here are some tools and equipment that you may need to buy: jack and jack stand lug wrench needle nose pliers standard and cross tip screwdrivers socket wrench with sockets from 1/4" to 1" in size 00:49 If you plan on doing brakes all of the time, you m ay want to add these things to your tool list: caliper spreader brake spring pliers brake adjusting tool brake bleeder hose brake cleaner 01:07 Set the emergency brake and make sure car is on level ground. 01:13 Remove the lug nuts and tire. 01:20 The part on top of the brakes is the brake caliper. 01:25 Using a 12mm socket, loosen both of the bolts located on the inside portion of the brake assembly. Remove the two bolts by hand after they are loose and place somewhere safe so as to remember which bolt went on top and bottom. 01:50 After you remove the bolts, set the caliper upside down on the brake assembly being very careful not to kink the brake hoses. 02:00 Pull the brake pads out and install the new brake pads. 02:08 Place the old brake pads in the upside down caliper and place the caliper spreader between them. Open the spreader until snug. 02:22 Flip the caliper over and break the brake bleeder valve open and with more pressure exerted on the pads by the spreader, use a container to capture the old brake fluid. Once you meet resistance, stop applying pressure. 02:53 Next, tighten bleeder valve back up and remove the caliper spreader and remove old brake pads from the caliper. 03:07 Place the caliper back to it’s original position over the brake pads and install the top and bottom bolts by hand (to avoid cross threading) and snug with the socket. Replace tire
