Huggable Clutched April 17, 2003 Share April 17, 2003 Thinking it's safe to drill your disc brake rotors? Mechanic assured that it won't crack?

Cool Neutral Newbie April 17, 2003 Share April 17, 2003 Cannot anyhow drill.. at high temperature, the disc will break apart.. Very danagerous.. How come that Kia lover gone nuts ?? Now he has to spent more money. All performance discs are tested under vigourous conditions.. if so simple, where got market for it. Link to post Share on other sites More sharing options...
Flaser Neutral Newbie April 17, 2003 Share April 17, 2003 Yes, a search on the web will show many people warning against this practice. When it comes to brakes, better don't anyhow pray pray... The lower end cross-drilled rotors are not that expensive anyway, provided they one for the particular make and model. Link to post Share on other sites More sharing options...

Phalanx Neutral Newbie April 17, 2003 Share April 17, 2003 Yes...but heard that though it is not safe to drill your OEM rotors, it is ok to slot it. Although I seriously have my doubts, might as well go buy Brembo. Link to post Share on other sites More sharing options...
Huggable Clutched April 18, 2003 Author Share April 18, 2003 I was *seriously* toying with the idea of drilling the discs, maybe not so many holes, a bit like those on the current S-class. Even got the contact and quote from some forum guy who did it. Yeah that Kia lover couldn't find x-drilled rotors for his Mentor, likewise there's no drilled rotors for my Sephia in the market also!

Huggable Clutched April 18, 2003 Author Share April 18, 2003 Any workshop does slotting of the rotors? Is it actually save to drill "halfway" or slot "halfway"? Link to post Share on other sites More sharing options...

Cool Neutral Newbie April 18, 2003 Share April 18, 2003 Have you tried BVO automotive.. they are brake specialise. I think I have seen a KIA with slotted brakes at their workshop.. It is at Blk 15 Sin Ming.. next to Angie Link to post Share on other sites More sharing options...
Sky8807 1st Gear April 18, 2003 Share April 18, 2003 Was wandering, how much benefit you get compared to not drilling the disc at all. Link to post Share on other sites More sharing options...
Saaber Neutral Newbie April 18, 2003 Share April 18, 2003 Don't do it....your rotor will be out of balance if not done properly and will crack very easily...... Link to post Share on other sites More sharing options...
Wrxblue 1st Gear April 18, 2003 Share April 18, 2003 Quote Thinking it's safe to drill your disc brake rotors? Mechanic assured that it won't crack? This Kia lover got his front rotors drilled, and the disc cracked! Evidence follows... Please note that: all original cross drilled brake discs in the market are cast with the holes rather than being drilled. Drilling after casting will cause heat affected zone around the holes and this would develop heat affected stress concentration around the holes. Hence it is most likely that it will crack once induced with the stress and heat from braking process. So only use original cross drilled brake discs not those being drilled by workshops or users.

Phalanx Neutral Newbie April 19, 2003 Share April 19, 2003 I think it is best if you buy purpose built rotors. Safer. Brakes, don't play play. Link to post Share on other sites More sharing options...
Madarmour Neutral Newbie April 20, 2003 Share April 20, 2003 Quote Any workshop does slotting of the rotors? Is it actually save to drill "halfway" or slot "halfway"? If you must have x-drilled/slotted discs, get new ones. It's not a very nice thought that the brake fails when you need it most! Cheers! Link to post Share on other sites More sharing options...
Modeldriver Neutral Newbie April 20, 2003 Share April 20, 2003 Can't agree more. Things that keep you safely in control of your mean (and not so mean) machines cannot play play ↡ Advertisement Link to post Share on other sites More sharing options...
