Brake Upgrade Information
- Thread starter donki
- Start date
I pay about $50 as well (ala a slab of beers), not a lot of places will like to do so though for safety etc. Just saw its for display/track or something. I went to a local engineering workshop and gave exact measurements so they know exactly what/where to drill so it was easy for them to punch the digits into the PC and away the machine went
70/30 from what I've read is a starting point for brake bias. Different cars will require different brake bias granted, but I think 91/9 isn't quite right.
What else, if not the brake prop valve could attribute to this?
There are a fair few people on Colt UK and mivec.co.nz who have had some kind of issue with the brake prop valve and have been trying to source ones from a Cyborg etc

I think you just need to accept that Mitsubishi knew what they were doing when they picked the proportioning valve to use. But you could try rebuilding your rear calipers.
Interestingly I had a look at the part numbers for the CJ4A since you mentioned the cyborg and turns out all big brake CJ4A models (asti-rs, mirage cup, etc) used MB699551 which is the sedan/Evo 3 proportioning valve so maybe that would give you the brake bias you are after. MB699551 has a split point of 2.95mpa whereas MB699641 has a split point of 2.45mpa

For the price of pads that will give good bite on stock brakes, you could afford a big brake upgrade which will work better than just better pads. Yellowstuff, Greenstuff, Project Mu etc are the go-to's.
Does anyone know if the front brake calipers from a CJ Lancer can replace the 276mm twin pots that people use from FTO, early Evos etc?
One of my front brake calipers has seized and I am trying to decide whether to try and rebuild it or whether to try and find calipers from a newer model Mitsubishi that are a direct fit

I would assume there should be fluid in them but it could have drawn humidity.
How tight are the tolerances though for pistons in the calipers? Might not allow for wire brushing them.
I also don't know how I would get the pistons out if they are so seized that even a special brake piston retracting tool could not move them at all.
I could get FTO calipers and rebuild those, but if CJ Lancers that also have 276mm rotors (or any late model Mitsubishi) use the same calipers I would rather just use newer ones without rebuilding them and I would expect them to be fairly cheap considering the abundance of these cars.

Found some info saying RA and VRX brakes are both 294mm but are bigger than ES LS VR etc. That leads me to believe lower models may be 276mm but single piston as the VRX are also single piston. Some more info about VRX and RA being interchangeable amongst CJs:
FRONT.
No the discs are different.
Same outside diameter but different thickness and offset.
REAR.
Same size disc but different size drum due to the rear wheel drive in the RA.
Yes the brakes are interchangeable

Oh I didn't think of that. I forget is the car 5 stud? It is isn't it..
I wonder how hard it would be to get your hands on a set of the brakes and just see. Could always on sell for what you paid :/ other than that you'd be the first to try it haha

You might have to research it yourself, I can't say I've heard of anyone doing it.
Mini Cooper calipers are a big single piston caliper, if you were going to use those you may as well just get big single Magna ones, or step it up to the twin piston Magna/FTO calipers. At least we know those fit 100%.
