Question about 1985 Yamaha FZ 750 FN (Europe)

1 Answer

Brake pro OK now my problem: With the system bled, the brakes do not exert much force at all... I can push the bike with the brake lever fully depressed!!! I measured 4.7mm on the brake rotor (I think the absolute minimum in the manual is 4.5mm) I even see the pads pushing against each other, but Im not sure the displacement is sufficient. What could the problem be? How can I be sure that all the air is bled out from the system, or is there a problem in the master cylinder assembly that I am overlooking. BTW I rebuilt the master cylinder assembly too...new seals and everything.

You probably still have air in the system ... Back to bleeding ! start bleeding from the top down--banjo bolts down to bleeder--then let it sit for a few minutes and take a plastic hammer or a piece of wood and tap on banjo bolts to move air bubbles to top and bleed again.

How do i adjust emergency brake cable on 2003 jeep liberty sport. with 4 disc brake pads.


Remove rear wheels and the brake rotors. parking/Emegency brake shoes are inside these rotors. Check shoes if worn, replace them Your Emergency brake is self adjustable.

OPERATION
A hand operated lever in the passenger compartment is the main application device. The front cable is connected between the hand lever and the rear cables with an equalizer.

The rear cables are connected to the actuating lever on each primary brake shoe. The levers are attached to the brake shoes by a pin either pressed into, or welded to the lever. A clip is used to secure the pin in the brake shoe. The pin allows each lever to pivot independently of the brake shoe.

To apply the parking brakes, the hand lever is pulled upward. This pulls the rear brake shoe actuating levers forward, by means tensioner and cables. As the actuating lever is pulled forward, the parking brake strut (which is connected to both shoes), exerts a linear force against the secondary brake shoe. This action presses the secondary shoe into contact with the drum. Once the secondary shoe contacts the drum, force is exerted through the strut. This force is transferred through the strut to the primary brake shoe causing it to pivot into the drum as well.

A gear type ratcheting mechanism is used to hold the lever in an applied position. Parking brake release is accomplished by the hand lever release button.

A parking brake switch is mounted on the parking brake lever and is actuated by movement of the lever. The switch, which is in circuit with the red warning light in the dash, will illuminate the warning light whenever the parking brakes are applied.

Parking brake is self-adjusting when the lever is pulled. The cable tensioner, once adjusted at the factory, should not need further adjustment under normal circumstances.
REMOVAL
  1. Raise and support the vehicle.
  2. Remove the tire and wheel assembly.


  1. Remove the disc brake caliper.
  2. Remove the disc brake rotor.
Brake Shoe

  1. Disassemble the rear park brake shoes.
CLEANING - REAR DRUM IN HAT BRAKE
Clean the individual brake components, including the support plate exterior, with a water dampened cloth or with brake cleaner. Do not use any other cleaning agents. Remove light rust and scale from the brake shoe contact pads on the support plate with fine sandpaper.

INSPECTION - REAR DRUM IN HAT BRAKE
As a general rule, riveted brake shoes should be replaced when worn to within 0.78 mm (1/32 inch) of the rivet heads. Bonded lining should be replaced when worn to a thickness of 1.6 mm (1/16 inch) .
Brake Shoe

Examine the lining contact pattern to determine if the shoes are bent or the drum is tapered. The lining should exhibit contact across its entire width. Shoes exhibiting contact only on one side should be replaced and the drum checked for runout or taper.

Inspect the adjuster screw assembly. Replace the assembly if the star wheel or threads are damaged, or the components are severely rusted or corroded.

Discard the brake springs and retainer components if worn, distorted or collapsed. Also replace the springs if a brake drag condition had occurred. Overheating will distort and weaken the springs.

Inspect the brake shoe contact pads on the support plate, replace the support plate if any of the pads are worn or rusted through. Also replace the plate if it is bent or distorted.

INSTALLATION

NOTE: On a new vehicle or after parking brake lining replacement, it is recommended that the parking brake system be conditioned prior to use. This is done by making one stop, from 25 mph on dry pavement or concrete using light to moderate force on the parking brake lever.

  1. Reassemble the rear park brake shoes.
  2. Adjust the rear brake shoes.
  3. Install the disc brake rotor.
  4. Install the disc brake caliper.
  5. Install the tire and wheel assembly.
  6. Lower the vehicle.

No brake pressure


When you bled the system was fluid coming out the bleeder valves?
Where the bleeder valves closed off with the brake pedal fully depressed?
Is the fluid reservoir cap ok?
Is the master cylinder ok?

Hello I have replaced the clutch plates,the release cylinder seals and rebuilt the clutch master cylinder. There is no leaks and the system has been bled and it feels fine. When I pull the clutch lever in...


Back wheels often move when the lever is pulled in...this is due to hydraulic drag caused by the oil on the clutch plates and is totally normal. You should be able to stop the wheel by hand with the lever in.
With the lever out the clutch is fully engaged and the engine will therefore stall with the brake on...
As long as the wheel rotation can be stopped by hand with the clutch pulled in it's behaving normally...
Rocking the bike in gear is a method that's used to seperate the plates on a clutch that is dragging...usually if it's not been used for a while.

Rear brake lever doesn't push the brake pads against the rotor. New lines. Bled the brake using pressure, then suction, then using the pedal. Seems to bleed OK, but doesn't work when everything is...


Hi, remove the caliper from the rotor, leaving the brake line conected, now lift the caliper higher than the master cylinder and re bleed the system with it in the higher position, this will force the air out up hill rather than the fluid gravity feeding when you bleed it in the normal position, poor master cylinders on the rear brake, make sure your brake pedal returns fully check it isnt sticking and has some free play

MY BIKE HAS A SIX INCH STRETCH I GOT EVERYTHING HOOKED UP I BLED THE BRAKES AND IT IS STILL NOT WORKING AT ALL


hi,i am assuming you have no front brakes,bleed the master cylinder before you try the calipers,to do this,simply pump up some brake pressure with the lever,hold the lever against the bar (fully applied)then crack the banjo bolt that holds the brake line onto the master cylinder,you should see air escape,retighten the banjo bolt,repeat the procedure untill all the air is gone,it doesnt take much air to stop the master cylinder working,once you have the master cylinder bled,then rebleed the calipers in the normall fashion,dont forget to put a rag down to protect the paint on your fuel tank,brake fluid loves paint...hope this helps,,cheers

The rear drum brakes:
  • Have internal shoes that expand against the brake drum (1126).
  • Are a single-anchor type.
  • Are actuated by one rear wheel cylinder (2262).
  • Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
  • Adjust rear brake shoes and linings (2200) automatically.
  • Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.
When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .

Brake calipers spongy feel


Does all the usual tricks include wrapping a thick bungee cord around the brake lever and leaving it overnight? That should force any residual air bubbles to the top of the system where the master cylinder should replace them with fluid.

If that does not work try installing some new bleed screws, even speed bleeders.
