Hi guys,

I am in the process of upgrading my brakes and have opted for the following,

FRONT:

Wilwood Midilite Front Calipers (+ custom fitting brackets)
MGZS 180 282mm Front Discs
Ferodo DS2500 Pads


REAR:

DC2 Calipers
MGZS 180 260mm Discs
Ferodo DS2500 Pads


The car is originally an 1993 Civic LSi (Hatch), so comes with rear drums. So I have also purchased the front & rear EG6 hubs to do the upgrade.

However I have a few questions that hopefully you guys can help with,

1) I have not purchased my DC2 rear calipers yet, but was wondering would 2002 EP3 Civic Type R ones fit as I have some lying around. I believe they can accommodate the 260mm discs but hear that they have to be fitted the opposite way round which needs the bleed nipples are on the wrong side. Not sure how correct this is.

2) If I go with the DC2 rear calipers, will any year DC2 accommodate 260mm rear discs or just 1998 onwards. I know the front calipers on the 1998 onward are different but not sure about rears.

3) Handbrake cable - As my EG shell originally had rear drums I believe I will also need a hand brake cable from a rear disc model. Do I get an EG one to match my chassis or one from a DC2 to match the rear calipers?

4) Does anyone know the size of the brake master cylinder on the LSi. I am considering the upgrade to the 1” Cylinder from the DC2 / EK9 / MB6. Are all of these a straight fit?

5) I have also read about changing the proportioning valve. Do you think this is necessary on this brake setup. Or will I be okay with the stock LSI one.

6) The car has been off the road since 2005 and I can’t remember if it was ABS or not. There is no engine in the car anymore so is there anyway of telling if my LSI Civic has ABS or not? Does an ABS vehicle have more inlets on the proportioning valve?


Sorry for all the questions. :nono:

Thanks
 
Weird how nobody has answered this??

First off your setup looks great for any road/ track car. Deffinately some good choices.

1. Yes EP3 / DC5 rear calipers will fit onto the MG 260mm discs. But as you say they need to be fitted upside down, as in R to L to keep the handbrake cable in the right place. But there are other mods you need to do to make them fit. Only few small mods full details here.

2. No not any year will do. only JDM 98 spec onward had 260mm rear calipers. and All UK DC2's. 96 spec's have 240mm ones.

3. Best bet is to go with the EG6 handbrake cables. As all the mounting points will be right. If DC2 ones used then they will have same caliper fitment or if EP3/DC5 ones you can swap the Caliper handbrake mechanism arm over to suit or just mod the end to hold onto the lever. Is described in link above.

4. Upgrading the master cylinder is not a must but is advised. Using a smaller one will just make the pedal have more travel and not be as responsive. Using the bigger 1" one is suited to the bigger setups and will give alot better pedal feel and response. Think most are straight fit once you move your brake lines to fit. Best to get DC2 or EK9 one as the MB6 is a Lucas one instead of the jap NISSIN. Generaly considered better.

5. Im not 100% up to date with prop valves as there are so many different ones and so hard to tell which are what. But general rule is to make sure you have the Prop valve off a car that is fitted with front and rear brakes as standard. At least then the distribution is suited for full disc setups. Its mainly because the drum brake prop valve is not suited to a rear discs setup. If you don't get one you will end up with unbalanced brakes and the whole system won't be effective causing lock up ends as such.

6. Easy way to check for ABS is to follow the brake lines out of your master cylinder. If they all go into a box in the corner with a big elec plug on it then thats your ABS pump. If they go to prop valve then dispers around the car then No ABS.

P.s once you get a new 40/40 prop valve and 1" MC you will need to adapt your brake lines in the bay to fit. Even if you have Abs then would be good time to ditch the system if you want to save hastle.

No OEM prop valve will be ideal for you because of your front brakes, depending on what piston size you opted for. Most people opt for the largest under the (incorrect) assumption it gives them better brakes, and this usually requires an aftermarket adjustable unit to correct it.

Seen people in the US use prelude prop valve even with big brake kits as a cheap solution.
 
Well, any valve will work, in so much as the front brakes will work and the rears won't lock up, however it's the varying degrees to which the rear brakes will work that is of concern. Getting the right balance is the finishing touch on a brake upgrade, it'll reduce stopping distances, keep the car flatter under braking and improve handling whilst braking.
