Happy 70th birthday to my wifey.

During this pandemic, and yesterday and today in particular, this post learned from YouTube the following:

1.  Removal of the piston using water syringe;

2.  Use of syringe for bleeding the hydraulic brake set;

3.  Addition of mineral oil on older hydraulic brake set  (you remove the top cover, and simply pour the mineral oil on top;

4.  Simplified bleeding of the hydraulic system;

5.  The slight difference in brake pads of dual and quad piston (only one cm in length)

6.  That the braking force is affected by the radius of the brake disk - directly proportional...

     Hence the increasing in brake torque is smore affected by the disk size (diameter and radius)

7.  How to install new olive and insert when cutting cable hose, and or changing cable hose (as in some brakes like zoom have left to the rear, and right to the front.  You have to switch the hose between the front and back.

     Some methods:

     1.  Clamp the hose and hammer the metal part into the hose; and then insert the olive and have the 

          8 mm tube clamp press fit the olive.   

     2.  Buy the tool.   The olive and the insert, and the tool would not cost more than P300.00 I will order

     2. Use a press tool.   Instead of hammering the tube insert.
