HOW TO CHANGE YOUR DISC PAD

OF COURSE,  EVERY VEHICLE MAY HAVE DIFFERENT CONSTRUCTION OR DESIGN ON ITS  CALIPER BRAKE ASSEMBLE BUT  DISC TYPE BRAKE HAS THE SAME  PRINCIPLE.

THE  REPLACEMENT FOR THE DISC PAD IS A VERY SIMPLE JOB.

1.  MAKE SURE YOU CAR IS IN HANDBRAKE POSITION IF YOU ARE REMOVING THE FRONT CALIPER .., IF YOU ARE REMOVING THE REAR CALIPER , PLACE THE SHIFTING LEVER TO ANY GEAR POSITION..
2.  REMOVE  THE  TIRE WHERE THE DISC PAD IS LOCATED .
3.  NOW ,  THE CALIPER TYPE BRAKE SYSTEM HAS TWO PARTS:

                A.  THE FIRST PART IS BOLTED BY TWO NUTS (  17 mm ) TO THE BASE PLATE
                B THE SECOND PART IS  BOLTED TO THE FIRST PART BY ONE BOLT ( 14mm) either at the top of the first part or at the bottom of the first part, so it depends on the design. THE other end of this second part HAS A SHAFT ABOUT  4 INCH IN LENGHT AND IS INSERT TO THE FIRST PART. IT LOOKS LIKE A BOLT , SO DONT TRY TO USE  A  WRENCH TO REMOVE IT BECAUSE IT IS NOT A NUT, IT IS ONLY A SHAFT..   THIS SECOND PART IS WHERE THE  BIG PISTON IS PLACE .  THE SECOND PART IS THE ONE THAT SECURED THE TWO DISC PAD IN ITS POSITION.

4.  REMOVE THE NUT  OF THE FIRST PART THAT IS BOLTED TO THE FIRST PART  ( 14mm or 17mm ) located either at the top or at the bottom. This bolt is covered by a rubber booths.
5.  you can now SWING THE SECOND PART.  REMEMBER THAT THE  ONE END OF THE SECOND PART IS NOT BOLTED BUT IS ONLY SECURED BY A SHAFT TO THE FIRST PART.

6. HAVING REMOVED THE NUT OF THE SECOND PART, USING A BIG SCREW DRIVER , INSERT IT TO THE OPEN HOLE OF THE SECOND PART AND TRY TO DISPLACE OR SWING  IT FROM THE FIRST PART.   THIS SECOND PART WILL NOT BE TOTALLY REMOVED FROM THE FIRST PART BECAUSE IT IS STILL SECURED BY A SHAFT THAT IS WHY YOU CAN SWING IT BACK AND FORTH.

7. AFTER DISPLACING THE SECOND PART, OR SWINGING THE SECOND PART ,   THE DISC PADS WILL NOW BE EXPOSED.
8.  THIS IS SIMPLY INSERTED ON BOTH SIDES OF THE DISC BRAKE ITSELF.
9.   SIMPLY REMOVE THAT TWO DISC PAD  IT BY HAND,   NOTE OF ITS  ORIGINAL POSITION.
10.  REPLACE IT BY THE NEW DISC PADS.  
11.  SWING  BACK THE SECOND PART AND PUT BACK THE NUT.


THERE IS A POSSIBILITY THAT THE WHEN PUTTING BACK THE SECOND PART , YOU MAY FIND IT DIFFICULT TO EXACTLY PUT BACK THE SECOND PART BECAUSE THE PISTON END IS TOUCHING THE DISC PAD OR THE DISC PAD IS BLOCKING THE THE PISTON END.

THIS MAY HAPPEN BECAUSE THE PISTON END HAS  LITTLE BIT MOVED OUTWARD BECAUSE OF THE DISC BECAME THIN .

IF THIS HAPPENS , DO THIS.

1.  GET A  C CLAMP .
2.  INSERT THE FIXED END OF THE C CLAMP  AT THE BACK OF THE SECOND PART AND THE MOVING THREADED PART ON THE INNER END OF THE PISTON.
3.  GET A  VISE GRIP ,  CLIP IT HARD TO THE BRAKE HOSE  .LOOSEN THE BLEEDER NUT OR EVEN THE  BIG NUT OF THE BRAKE HOSE BOLTED TO THE SECOND PART, THIS IS TO MAKE THE PUSHING OF THE PISTON BACK  EASIER BECAUSE THE AIR CAN EASILY COME OUT
4.  TURN NOW THE C CLAMP CLOCKWISE TO PUSH BACK THE PISTON .
5.  PUT BACK THE NUT OF THE HOSE, AND THE BLEEDER VALVE.
6. REMOVE THE VISE GRIP.
7.  PUT BACK THE SECOND PART TO ITS ORIGINAL POSITION.
