vented disk upgrade.
« on: August 02, 2011, 09:58:24 pm »
The '92 golf needed brakes very badly so I bought vented GTI disk and pads to fit. GTI pads are thinner to compensate for the thicker disk but appearantly I have the wrong calipers because even though I compressed the piston completely I can't get it to fit over the disk/pad assembly.

Anyone know if that's what's going on here?

'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.

I did the swap on my jetta and I thought all the calipers were the same on the solid rotor cars. Mine were a bit tight, but they went on. Maybe try a bigger hammer and let the extra burn off slowly while driving???

So I looked into it more and I've got PBR D539D pads which are for vented rotors and 25243 vented brembo rotors.
The pads fit in the carrier perfectly with the rotor in place but when I try to put the caliper on there's at least an 1/8th inch of interferance and I'm sure the piston is compressed all the way..........



Anyone know if euro golfs have a slightly different caliper than USA models?

Ok I found some calipers off a solid rotor jetta to compare.

The jetta ones are wider and fit over my rotor/pad setup >:(. So vw did a weird thing and put solid rotor only calipers on my golf. I could use the jetta ones I found but they're well used already so I'm gonna price new ones.

Rockauto has some loaded calipers for around 40 dollars. That is what is on my car. I have a Rockauto code as well for a little off the total too.

my 92 jetta, i went from solid disks to vented ones, didnt have to change the pads (mine were worn just right) but it all fit together just fine..

the calipers liked the new hardware just fine..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Yeah I'll have to look into some wide calipers, the brakes that are on it are way junk and I'm not gonna buy new solid rotors.

we used to retro fit all the mk2 taxis that we were servicing so they would brakes that lasted more than a couple of weeks. discs and pads fit right in.
the worse one we saw was 1 week, 11,000 kms, worn to the metal.
