DRUMS TO DISC...

6FIVE_STANG · Oct 13, 2006

i currerntly have all manual drum brakes and im in the process of ordering a Granada front disc brake kit. I noticed that it doesn't inlude a booster because there manual brakes. Is it possible to make this kit into power brakes instead of manual brakes just by adding a booster??...
- if so, what do i need to do?..
- if not, what do i need to do?...

P.S. im trying to get everything by next Saturday, so please give me all your opinions a.s.a.p!...thanks

Automatic or manual? What transmission? For manual cars your out of luck unless you want to give NPD $300. Automatic cars can use a 87 Mustang LX coupe 2.3 booster, goes right in.

I have an 1965, automatic, C-4 tranny.

6five_stang,
I just did this same thing with my '65 289, c4. I don't know where you're getting the kit but you can get it from discbrakeswap.com. He's also on ebay. I don't remember exactly but the whole kit was like $550 give or take a few. New mc, spindles, calipers, pads, prop. valve, instruction cd,...everything you need. The guy is awesome for answering questions and helping you out. Highly recommend. Now to your question. Yes. I stayed manual due to the fact I wanted to keep the manual feel for the car and a new booster is around $250 You will also need to run a vacuum to the intake for the power booster. You may encounter problems pulling enough vacuum at idle depending on the cam which you will need to buy a canister from what I have read. Search the internet for this. (Booster can be added later if you want) Also, manual brakes stop the same whether the car is running or not...nice if you've ever had one stall. You'll have to re-route some brake lines, no big deal just don't kink 'em. You'll need adapters to get the brake lines into the granada mc. Email me and I'll tell you where and part numbers to avoid a lot of time searching. It's pretty simple and straight forward. Again, Dennis at discbrakeswap.com is awesome. Check your ball joints and tie rod ends. If they are worn out now is the best time to replace 'em. Let me know if I can help in any way. I just finished this with a lot of other stuff and have turned a lot of wrenches in the past three months and can hopefully save you some time. One more thing, is your car original I6 or 289?

NPD's booster for manual tranny cars sucks because of major clearance issues with the MC. A better option is MustangSteve's modified pedal, but you must modify the clutch linkage as well.

Didn't know that. I know people have had good luck with the conversion boosters, maybe it was MustangDepot that had the good one? As for MustangSteve, that's why I didn't mention it, but it's a good canidate for an auto or 5spd car.

Cannoball888 · Oct 14, 2006

MustangDepot's probably works better because they come with a low- profile flat top MC that clears the export brace.

The install of an 87 Mustang booster (used on most 80's FOX bodies) is not a "goes right in" proposition. Its install requires some mods to the firewall, pedal, and pedal bracket and is not applicable to cars with unmodified manual clutch linkages. MustangSteve sells parts and pre-modified parts for this job.

The '87-'93 2.3L & 5.0L brake boosters are not direct bolts-ins, but mods are not terribly difficult, boosters can be purchased at parts stores for ~$80 dollars (~$20 at wrecking yards), and they work really well.

On '65/'66 Mustangs, it doesn't matter which Fox booster type is used (2.3L or 5.0L), either style Fox booster will block the hole in the firewall where the mechanical linkage would go through (for a manual transmission).

If you have an automatic, it doesn't matter if this hole is covered...for obvious reasons. If you have a standard trans, then you can use either type booster with a cable-actuated clutch.

If you have a '67-'70 Mustang, you can use either 2.3L or 5.0L booster versions. A 2.3L booster will block the linkage hole in the firewall, but the 5.0L booster will NOT. With the 5.0L booster, you can use a cable clutch, hydraulic clutch, or even the original mechanical linkages.

I changed my '70 with manual drums all around to front Granada discs a couple years ago. I didn't put a brake booster on it. I think it works great as is. Unless you are absolutely positive that you have to have power brakes, I would recommend that you install the Granadas onto your existing system and test them out before buying more parts.

"...You'll have to re-route some brake lines, no big deal just don't kink 'em. You'll need adapters to get the brake lines into the granada mc..." Duane

If you don't have to use brake line adapters, don't. Every connection point is just another place for potential leaks, plus adapters just don't make for clean looking installations if you don't have to use them.

The '65/'66 Mustangs have 3/16"-24 inverted brake line fittings on the front where the hard line connects to the flexible brake hose. If you install Granada front discs, then you have a problem at this connection point because the Granada's flex hose fitting size is 7/16"-24. The '67-up Mustangs have the correct size fittings on the ends of the hard lines to connect to the Granada's flexible brake hoses.

This 7/16"-24 brake line fitting size is also used on a couple of the ports of the Granada's proportioning valve.

If you are using the Granada/Maverick MC, the port sizes on them are 7/16"-24 on the front port (port ot rear brakes), and 9/16"-18 on the rear port (port to front brakes).

The early Ford vehicles primarily use (4) different size inverted brake line fittings: 3/16"-24, 7/16"-24, 1/2"-20 & 9/16"18 inverted fittings. The 3/16"-24 inverted flare fittings are easy to obtain from any auto parts stores. However, the remaining line sizes can be very difficult to locate since most auto parts stores do not carry them.

I was fortunate enough to have a chance to buy a bunch of brand new 7/16"-24, 1/2"-20 & 9/16"18 inverted line fittings at a reasonable price. If anyone is needing any of these sizes and can't find them locally, I have plenty.

Ultrastang, I would be interested in the fittings for the granada mc to adapt the 3/16 lines as I am now using t-blocks and having to block one end. It's all I could find. As far as the flex lines on the granada swap, discbrakeswap.com sends a kit with the correct lines. You remove your current lines (flex) and install the ones in the kit to the caliper and your 3/16 hard line fits into it. Plug and Play. The prop. valve with the kit is ready to accept the 3/16 lines also. That kit is great b/c it includes everything you need except the mc fittings. Good info in your post for anyone doing the swap. Once again I would love the granada mc adapters to fit the 3/16 hard line so I could remove my t's. PM me and I'll buy a couple from 'ya. Thanks,
Duane

Most auto parts stores offer the fittings. They are contained in a drawer/cabinet display in most stores. The common Weatherhead or Everco part number is 7818 for the 1/4" to 3/16" adapter (female 3/8"-24 to male 7/16"-24) and 7830 for the 5/16" to 3/16" adapter (female 3/8"-24 to 9/16"-18). They also have lenghts of tubing with different fittings on each end that do the same job. The fittings are available from rockauto, do a parts search. I am working on a custom master cylinder with correct fitting machined in (I testing it now). I will eventually include the MC lines in the kit.

blue65coupe · Oct 15, 2006

Degins, unfortunately the key word is most. I've never seen rockauto's site. Thanks, I'll check 'em out. Let me know when you get that mc working. I'll be a guinee (sp) pig. Seriously. Hey, I got the part yesterday. Thanks. I'm going to work on 'em this week and I'll let you know what happens.

Ultrastang, sent a reply. Thanks

6five_stang, did you get my replies? Was it clear? Let me know if you have any more questions.

Rusty67 · Oct 16, 2006

I havn't done the swap myself so correct me if I'm wrong but the 5.0 booster from 87-93 doesn't require any modification to the firewall or pedal support ?

Cannoball888 · Oct 16, 2006

Requires pedal mod
