What is the rate for traveling in a four cylinder vehicle

Too fast. 2100 mph

Did you get a good bleed with fluid coming out at all four wheels? If they bled good, and the pedal still goes to the floor, you need to check the brake master cylinder-it is probably shot with an internal leak. An internal leak will not let fluid pressure build up, so no brakes.

Did you keep the brake fluid reservoir from going dry while bleeding? If it went real low, air might have got back into the lines.

It is not uncommon when bleeding brakes on an older vehicle for the master cylinder to suddenly develop an internal leak and require replacement . Here's why: pushing the pedal all the way to the floor causes the master's piston to push in farther than ever before. The rubber cups then travel over a section of the cylinder not usually touched by the cups-old fluid can develop a crud there and when the piston pushes over it, the cups can get ruined. To avoid this when bleeding brakes, put a short piece of 2X4 wood block under the pedal. Then the pedal will not extend the master's piston beyond it's normal travel. Of course on a new master cylinder, you do not have to do this. A new master cylinder does require bench bleeding before installing, however, to ensure no air pockets develop from there.

Yes its the brake booster if when the pedal travels to the floor you hear a vacum sound everytime.

The valves for any given cylinder will be closed when that particular cylinder is at TDC and on the "firing" cycle. Since 4 cycle engines have four "cycles" the piston can be at TDC twice. Once for firing and once when the exhaust cycle is completed and the intake cycle is starting.

Cycle 1: Intake valve is open and piston is travelling DOWN. (Intake)
Cycle 2: Both valves are closed and the piston is travelling UP (compression)
Cycle 3: Fuel has been ignited and the piston is travelling DOWN ( power)
Cycle 4: Exhaust valve is open and the piston is travelling UP (exhaust)

TDC is Top Dead Center, or the point that the piston is at the top of it's travel.

1342..firing order...distributor turn counter clockwise....

brakes pads go with calipers and disc brakes,brake shoes go with drum brakes which has wheel cylinders.

Firing order 1-2-3-4-5-6 ------- front | 1 3 5 | of | | vehicle | 2 4 6 | ------- distributorless ignition NOTE THIS IS FOR THE 3.6L

12x60=720 meters in one minute the distance traved is 720 meters in one minute so in four minutes the vechilce has travled 720x4 minutes =2880 meters in four minutes.

Please don't forget to rate:


Bleeding The Brake System Bleeding When any part of the hydraulic system has been disconnected for repair or replacement, air enters the lines causing spongy pedal action (because air can be compressed and brake fluid cannot). To correct this condition, it is necessary to bleed the hydraulic system to ensure all air is purged.
Always begin bleeding the brake system from the furthest wheel cylinder or caliper from the master cylinder; the right rear.
NOTE: The right side of the vehicle is the passenger side. The sides of the vehicle are determined from the driver's perspective. This reference is taken from sitting in the driver's seat, facing forward.
Maintain a full reservoir during the bleeding operation. Never use brake fluid that has been drained from the hydraulic system, or from an open container, no matter how clean it is. Always use brake fluid from a new, sealed container. The front and rear reservoir will drain as the front or rear brakes are bled.

1. Park the vehicle on a level surface. Place the vehicle in PARK (automatic) or REVERSE (manual) with the engine OFF, and apply the parking brake. Chock the rear wheels to prevent vehicle movement. NOTE: Wheel chocks may be purchased at your local auto parts store, or a block of wood cut into wedges may be used.
   
2. Loosen the lugnuts from all four wheels, but do not remove the lugnuts until the vehicle is raised and supported properly.
3. Use an approved jack and raise the vehicle high enough to place jack stands under all four corners of the vehicle. Place the jack stands under the frame or axles of the vehicle. Ensure that the front of the vehicle is raised higher than the rear.
4. Remove the wheels from the vehicle.
5. Clean all dirt from around the master cylinder fill cap. Remove the cap and fill the master cylinder with brake fluid until the level is within 1/4 in. (6mm) of the top edge of the reservoir.
6. Clean the bleeder screws at all four wheels. The bleeder screws are located on the back of the brake backing plate (drum brakes) and at the top of the brake calipers (disc brakes).
7. Attach a length of rubber hose over the bleeder screw and place the other end of the hose in a plastic jar.
8. Have an assistant place and hold pressure on the brake pedal.
9. Open the bleeder screw 1/2 - 3/4 turn. As the bleeder is opened, the brake pedal will travel to the floor. Have the assistant inform you when the pedal has bottomed out. NOTE: Do not remove pressure from the brake pedal once it is bottomed out. No movement to the pedal should occur until the bleeder is closed and the assistant is made aware of the situation. Failure to do this will draw more air into the system.
   
10. Close the bleeder screw and tell your assistant remove their foot from the brake pedal. Continue this process to purge all air from the system.
11. When bubbles cease to appear at the end of the bleeder hose, tighten the bleeder screw and remove the hose.
12. After bleeding each wheel, check the master cylinder fluid level and add fluid accordingly.
13. Repeat the bleeding operation at the remaining three wheels, ending with the one closet to the master cylinder. The pattern is, RR, LR, RF, LF.
14. Fill the master cylinder reservoir to the proper level and install the reservoir cap.

Hey there janandshane,

I've got a 91 Wrangler, lots of fun. Here's your info.

Viewed from above, front of vehicle on the right side, cylinder locations are:
6 5 4 3 2 1 for a six cylinder and 4 3 2 1 for a four Cylinder

The firing order is:
1 5 3 6 2 4 for the six and 1 3 4 2 for the four.

The distributor rotation is clockwise.

To find Top dead center (for wire to cylinder #1 on distributor), look for and line up the timing marks on the crankshaft (front of the engine).

Or, pull the #1 spark plug, stuff the hole with a cork or a rag. Slowly crank the engine until the cork pops out.

Pull the distributor off. The rotor is pointing where the plug for cylinder #1 should go. The rest of the wires go in the firing order clockwise.

That about covers it.

Remember: Good things come to those who rate. How about a nice FixYa?
