of course....! my apache150 has had a replacement of the master cylinder and the pads..yet the bite was spongy to say the least...seems like my disc is beyond the 'sharp bite' period....so yeah a disc replacement is on the cards...

my bike has clocked 20k kms....and I use my front disc so much that i have never had to replace the brake shoes at the rear but have replaced my disc pads...

The Discs usually don't need any replacement unless it gets rusted or due to manufacturing defect OR due to any accident.

**vinfreak** · 10-31-2008, 03:25 PM

Yeah..Mithun is right..Discs dont need replacement. If theres lack of bite then there must be some problem with the assembly of the entire Brake system..
On a comparo..you change the Brake shoes for a Drum brake..but seldom the Drum itself unless you have some damage to the drum..likewise Change the Pads or the cylinders for Discs and it should be as good as new..

^^^

I beg to differ....atleast....my disc needs a replacement...maybe a manufacturing defect..but thickness of the disc has gone down....

Sai, rubber pads cant scrape metal disc.

Unless there is deformity in disc's shape(manufacturing fault) & or it has got deformed in an accident, Disc does not need replacement.

without unusual reasons, the disc certainly doesnt need a replacement at 20K. Excessive use of worn out pads ( which is when the matalic part rubs the disk) may also cause disc damage.

Usually disc dont need replacement, but in case pads are badly worn out, the calipers can damage the disc and then a replacement will be on card.

disk pads are made of rubber

**sai_ace** · 10-31-2008, 06:36 PM

I dont think so...some material similar to asbestos...asbestos was discontinued as it was carcinogenic,,,,

i expected the same .. but he told metal so i got confused ..
rubber cant form scratches on metal plate ,,

Quote from wikipedia: "Brake pads are steel backing plates with friction material bound to the surface facing the brake disk."

If the pads wear out too much, the underlying steel gets exposed and this is the part which damages the disc. You will hear a krrrrr sound when braking if the pads wear to this extent.
This kind of damage to the disc can be repaired by grinding the disc (or polishing?), unless the damage is too much.

incase you are referring to my post, I meant that when the pads wear out, the metallic part that holds the pads (I am not sure if you can call them callipers). will start scratching the disc. used the word "metallic part" for the lack of knowledge about what it is actually called. sorry for the confusion.
