Brake Shudder

[Kuran]

Hey guys,
When I apply the brakes there is a considerable amount of shudder coming through the pedal and there seems to be a bit of inconsistency. I've heard that machining the discs fixes this problem, any ideas?? I'd appreciate a quote on fixing this too if any of you guys have encountered the same thing. Cheers, Kuran

Yeah your discs could be warped.

Can you get slotted/cross-drilled rotors machined?

Can you get slotted/cross-drilled rotors machined?

Yep.

[Kuran]

how much do you rekon it'll set me back?

[bduffman]

get gpx calipers and master and get slotted rotors there not cheap
Look up dba rotors I need some to but got no money I can get them cost price though

A few years ago I got the stock rotors machined for around $25 I think, shouldn't be much more than that now.

Anyone know the minimum diameter on the discs?

Mate I had this problem really bad when I bought my beast.
I ended up replacing the rotors and pads..
Put slotted RDAs and Bendix CRTs on.
Not too expensive and stops like a dream now

[Kuran]

Thanks for the advice guys, appreciate it. I'll look into it over the weekend

Lol. I had rotors machined, brakes bled and new pads installed for a carton of piss by a mate who works at beaurepairs. So on the mainland, should only cost $50?

276mm - GPX & GPvR.

I spent every last cent i have on my fto so until saturday I can't even afford petrol . I'll have some big $$ though when i sell my other car

The RDA slotted rotors are well priced and will stop that problem occurring unless you are crazy on the brakes. Unfortunately, stock GR/GPX rotors warp fairly easily. If you get them machined, theyll be OK, but if you are heavy on the brakes, theyll just warp on you again. I think the RDA's are around $220 for the fronts from memory and are well worh the outlay (better braking and less chance of warping). You shouldnt need to replace the rears as they are unlikely to warp (they do a lot less work when braking).

I got my rda slotted rotors for 180 I think just shop around

[dstocks]

even better.....

[Kuran]

Are the standard DBA425 rotors any good (in terms of long life and not warping and things)? I don't brake that hard unless i'm having play time Would they be worth my money though or am i better off paying 100 bucks more for slotted?

[aza013]

Slotted foe the win.
It's better to have them there when you need them not wish that you had put them on when your breads fall away.

Avoid the 400 series full stop. They're just standard rotors slotted or drilled to order. You want decent ones, the 4000 series is the only way to go.

DBA's website says the 4000sl's are 300 bucks each
