What do I need to complete this changeover from drums?

 

the easy way to go is just to get the whole rear trailing arm assembly from a eg civig si, del si, or del sol vtec and change it over... thats what i did with my del sol, and it only took about 2 hours with air

oh ya, you will still need the rubber brake lines, e-brake cables, prop valve, master cylinder, and all that other little random **** from the car that came with the discs before

 

cool, i was worried about the other little things. just needed to know what ot look for when buying the disc brake conversion setup

 

will he need the master cylinder?

 

The larger master cylinder isn't a necessity, but it will help reduce pedal travel. I ran with ITR brakes and a 7/8 master cylinder and loved it. It's more of a preference issue than anything.

 

oh ok, thanx

 

Where is the proportioning valve located?

 

The proportioning valve is located in the center of the fire wall. It has 6 different hard brake lines screwed into all sides (can't miss it).

The rear disc suspensions are a direct fit swap from all 94-00 integras. The proportioning valve can be from any NON ABS 90-00 integra. I recomend buying the whole kit (prop valve included) form import auto salvage. They guarantee their parts, and their customer service is great (click here to buy)...

A larger master cylinder is ONLY required if your swaping your front brakes for larger ones. If you do experience added pedal travel from your rear disc swap it is ONLY because there is still air remaining in your brake lines. I know from experience as I did not switch my MC when I did my 94cx rear discs, and my brake pedal was still rock hard.

SWeet. Thanks for the info! But you mean for the MC, you need it only if you are going to get aftermarket bigger gsr brakes for the front? What about the brake booster then too?

What 94eg! posted seems a bit misleading. You may want a larger M/C to compensate for the increase in caliper piston size (regardless if it's in front or in rear), otherwise you can end up with a fairly "long" pedal before any significant braking occurs.

Some people don't mind using a smallish M/C and deal with the longer pedal throw, some don't like it and change it for a larger one. Your results may vary.

Civic/Integra rear disc calipers don't have a larger piston area than their rear drum counterparts. The "wheel cylinders" inside drum brakes have dual pistons that are equal in surface area to the single piston inside the rear disc caliper. This is why both the 95 Civic Si (rear disc) and 95 Civic CX (rear drum) both share the exact same master cylinder, and brake booster.

I swapped in integra rear discs on my 94CX and noticed NO change in pedal travel after proper bleeding.

I wouldn't exactly say aftermarket since Integra/Civic-EX brakes are still OEM, but you are correct. Since Integra/EX front calipers have larger pistons, you will need a larger master cylinder to match.

The brake booster, in my opinion, doesn't matter. If you were going to replace your master cylinder, you would be better off buying a brand new one that fits your existing brake booster (there are three different size MCs that fit the stock "small" civic booster). Adding a larger brake booster will actually give you less feedback from your brakes and make them a little harder to modulate.

Yup, with no piston area change there will be no difference in pedal stroke. Gatcha.

 

you guys kick ***

DC2 INTEGRA GSR REAR DISC KIT aren't these alot bigger then the front discs on a 94CX? would the front discs need upgraded as well since the car is front wheel drive?

 

The pistons in the rear calipers are the same size for either application, I'm pretty sure. Not positive the calipers are the same, so that swap would not warrant the change of M/C if one was happy with the original feel.

The rotors, caliper mounting, etc, might be different shifting the brake-bias around, which is a different matter altogether.

What does FWD have to do with this? Are you talking about weight distribution?

No...

The rear discs on a 92-95 Si are the same parts as all integras (except type R). The 92-95 CX has the same front discs as the 92-95 Si. This means a rear disc swap will upgrade your CX to Si style brakes. As long as you change the proportioning valve, you will be set for the weight distribution of your car.

If you swap your D series motor for a heavier B series, that is when you will need to upgrade your front discs & master cylinder. The 94 DOHC VTEC Del Sol uses the larger 93-95 Civic EX front calipers and a 7/8" master cylinder to handle the heavier front end with the larger motor.

Crap, I shouldn't have even brought that up...

 

so what about the parking brake cable? the one for disc is different that that of drums. Do you have to get two new lines from the disc-car if you are doing a rear conversion?

The 94-97 and 98+ non-abs Integras use different prop valves. They are not the same.

Thanks for pointing that out. I was not aware... 90-97 will work then...

u only need the brake booster if you're running a integra MC, if you dont want to change the booster just run a 94 4door civic ex MC and it'll work fine w/the stock civic booster

You will only want to change the MC if your going to be upgrading your front brakes. Don't even mess with it all if your not changing your fronts...

 

I understand why you swap the MC, but why do you need to switch the prop valve.

platinum.

 

there are a lot of people who do swap the prop valve and still brake fine. i know at least a dozen people who did not swap out the prop valve and have no problems with braking after swapping in rear disc.

 

I believe that the rear disc prop valve allows the rear discs slightly more pressure than the drum prop valve. If that is the case, then it would allow your rear tires to do more work, decreasing stoping distance...

It is still yet to be proven what the difference in valving is between the 30/30 (drum valve) & 40/40 (disc valve). There is definently a difference though...

 

so if the car brakes fine dont worry about it.

if not replace the valve.

platinum.
