Marks on 3G 10 Groove Disks...

[Monkfish]

I've got some strange marks on my 3G disks that I noticed today whilst on the faff with the D2's...

They look like they've glazed over, but it's odd that it's so patchy. For info, pads are Mintex 1144's, running Dot5.1 through Mr Burwash's fantastic braided hoses.

Ideas if you will please...

Esshh, now you're asking... **Checks**

Fitted them 25th May, had a track day shortly after fitting and I've covered best part of 2000 miles on them.

its due to the hard braking mate and the heat. mine were the same after santapod as i did brake very hard a few times after doing the 1/4mile run.

mine are a little more cenral on the disc but its nothing to worry about unless its like that all the time under normal conditions.
itll wear off with use mate, dont worry about it

I thought it might have been heat doing it, I do tend to 'make good use' of the brakes

I'm tempted to take the disks off and run a fine disk sander over them just to rough them up a bit. I might do the same with the pads as they may have gone the same way... Good idea or not recomended?

 

[dac69er]

not really worth it mate as long as the braking effeciency doeesnt seem to have been effected. should wear off in a month or so depending on how often you use the car.

yours have held up quite well really. just after about 3 hard braking sessions at pod mine were nearly as bad as yours are in the pics. i only have pagid pads though so that may make a difference

 

[Monkfish]

That's the thing, I've noticed the braking isn't what it was. It takes more pedal pressure to slow her down and the pedal seems softer.

 

[dac69er]

glazed discs shouldnt make it softer!? could be worth bleeding your brakes again to see if any air is getting in. may just be you thinking its not as good after being on a track.

you could try roughing them up a bit and see if that improves anything, no real harm in it as long as you dont grind loads of metal off or anything!

 

[Monkfish]

I think I'll bleed the system, perhaps the fluid is knackered.

should be changed every 3 years i think, could be less!

I thought it was 6 months for 5.1

 

[dac69er]

1st i heard of it!?!? wouldnt have thought it would be that often. think my starlet is due a change soon. might just do it after the winter as that will be when the moisture gets in!

if used for trackdays and heavy driving fluid should be changed on a yearly basis regardless of the type of fluid.

if for normally driving and occassional fast road (most people) fluid should be changed every 3 years regardless of fluid type.

 

[dac69er]

there we go then. want too far out. alos best to do it after the winter as thats when most of the moisture will get drawn into the fluid!

Every two years for brake fluid is the usual interval. Moisture is absorbed into the fluid naturally over time regardless of use.

 

[Monkfish]

Hmm...

I think I'll whip the disks and pads off and give them all a gentle rub down and replace the fluid while I'm at it.

Cheers for the replies
