[Mk2] [Generic] Rev 1 to rev3 brake upgrade

[TNM]

if its 7/8 is that bad?!

[cantfindausername]

7/8 will require more pedal travel to move the same amount of brake fluid as a 15/16.

Just done some quick sums, and if it takes .5" on your current MC to work the brakes to a set level, on a 15/16 it would take 0.42", so its about 18% difference. That may not feel like much, but when its piston travel, and not pedal travel, it might feel quite a lot different.

On the other side to this, it could give you a more progressive pedal, which personally I prefer.

Your call.

[TNM]

ahh thats not that bad then

[cantfindausername]

Certainly not as bad as some people have made out in the past.

[TNM]

good good.

Just sourcing the parts at the moment.

How much do you think is reasonable for just the calipers and sliders?!

[cantfindausername]

No idea I'm affraid. They can vary massively. You might get some that are in need of a refirb, or you could get some that have just been refirbed. I'm sure there will be some flaoting round the for sale section or ebay.

[TNM]

watching a few sets on ebay but they include discs and pads. But id rather stick new discs and pads in.

Been offered a set of calipers and sliders for £180 + postage

[cantfindausername]

Bit pricey if you ask me. But I've never really shopped round for them.

[TNM]

thats what i thought.

[cantfindausername]

I would think 100-120 tops for calipers and sliders. Especially if they're used.

[TNM]

hmm Rev2 calipers and sliders as well.

Offered £150 including postage.

[cantfindausername]

Sounds good. Cos postage could be a bit. Mind you, parcel2go would only be £13odd, so still a pretty good price.

Fingers crossed for ya bud.

[TNM]

Only changed the fronts in a nice warm garage
The start




Removing the caliper


And gone


We had to remove the stone gaurds as they are too small.

Trial fitting the disk



Old and new





And fitted with the wheel on




Will do the rears next week

[cantfindausername]

Good man. Looks like it all ran smoothly for ya

[MR2DIE4]

so if i read up correctly about the MC, i can install the full rev3 conversion and leave the old rev1 MC on till i find a good price rev3 one, whithout braking issues?

[cantfindausername]

you wont have braking issues no, but you will have to work the pedal harder to get the same braking force than if you fitted a rev2+ MC

[xavier]

not!

It is the ABS which gives the power of braking not the MC

[cantfindausername]

You what?

[xavier]

The MC do not control the force of braking but it is the ABS which automatically controls the force of braking of each wheel. The pressure is controlled i.e. that it decreases again when the point of blocking is close…

I have make the upgrade Rev1 brakes - > Rev2++ on my turbo and I did not change the MC.

Rear 280mm (EBC)




Front 275mm (EBC)



COOL

[cantfindausername]

Well thats the first time I've ever heard that. I'll be sticking to my theory though thanks.
