Hi I need new brake disk front and rear for my DR650 RSE 94. Is it the same brake disks like other tipe of DR650 and year's 92-95 models or it is different? I looked on Ebay and so just one tipe. So need your help befor ordering. Thx Alon G

Bleed the breaks untill you get clean clear fluid out of each one. start with the right rear, left rear, right front, left front. DO NOT let the reservor get low while bleeding. You can suck air into the lines and have the same problem. You need to do this immediatly as your brakeing ability is uncertain and can be un reliable.

Are they disk or drum brakes? Any leak is not good, need to replace either the caliper (front disk), cylinder if drum (rear).

Not knowing exactly what year & model makes this a question that really cant be answered correctly.
Some car years have drum brakes in the rear & some have disk, some have a single line from the master the goes to the front & rear & each "T"'s off in the middle letting equal pressure to each. Some have an individual line right from the master cylinder to each wheel. There are even systems called X systems that apply pressure in an "X" configuration (L front-rear RT / RT front.-rear L ) To get a more accurate answer, the make model & year should be listed as well if it has 4 wheel disk or not.

HERE IS SOME HELP

its disk all round but the parking brake is inside the rear disk and its brake shoes ,you will need a special bendix type brake adjusting tool to go through the back plate to turn the star screw type adjuster ,or make one with bent screwdriver

the fronts are definitly disk. If rear looks like front they are disk. If not which is more likely they are drum. Not an easy task. Might let the pros handle the rear drums.

The nut size is a 10x1.0

Sounds like the starter motor clutch is worn or damaged and should be replaced.
Go to the link below and scroll down and click on STARTER CLUTCH. An exploded view diagram and part list is given. All sections of the bike are covered. The starter clutch is not a serviceable item and is replaced when faulty.
Your Yamaha dealer should freely verify the noise if your on good terms with them.
Cheers!

If the rims are with spokes they use tube.If it has aluminum rims (like a street bike) then you can install tubeless tires

Yes the rear pedal operates the front RH disk as well.
When you bleed the brake do the front RH disk calliper first then the rear calliper.
Check that the pads are not beyond useful life and the not stuck.

Your 89 Corolla has drum brakes at the rear.
The graciousness of a FIxYa rating would be greatly appreciated.
