Wilwood Brake Upgrade Question.

[Wijns07]

I am looking to install Disc Brakes on all four corners on my car.

The Car is a 1969 Roadrunner. No power steering and no power brakes. I have 18" rims up front and 20" rims in the rear. (So should have plenty of clearance for the rotors.)

Please bear in mind that this is my non original / non numbers matching...pro-tour car.

I found a set-up on ebay that I was thinking about purchasing:

http://www.ebay.com/itm/WILWOOD-DIS...=Model:Roadrunner&hash=item33792a59b7&vxp=mtr

Has anybody else done this exact install off of an E-Bay disc brake kit? And if you have...is there anything missing in the kit that they are offering that I will need to purchase to do the install?

I'm also wondering if it would be better for me to purchase it from a different source than e-bay? (For cost and content of the kit?)

I would very much like to make the change to a power brakes set up I just don't know the parts that I'm supposed to order for that either.

Looking for your input.

Thanks

Wijns

Hmm,
Personally I would not purchase Wildwood or SBS for my classic muscle car...
UNLESS it was (is) a Resto MOD OR I was racing (SCCA Road Racing)

Why?
Wildwood is a bit more pricey. IMO...

But, if it is what you want, to be able to say you have Wildwood...then go for it.

Some people will say you should not use disc brakes with non power (manual brake) setup. I'm not saying it can't be done or shouldn't, just relaying what I've heard.

Others please chime in..

Check out these videos the website..
Also he sells a great booster and master cylinder...great to talk to as well!

Good luck!

It is his pro touring car, definetly use wilowood, price is not that bad.
I bought my entire kit from magnumforce.

you need:

spindles
hubs
rotors
calipers
caliper to spindle bracket
bearings
longer rear studs
mopar diff spacer bracket
rear rotors
rear caliper brackets
rear internal pads for park brake
rear calipers
stainless brake lines and tee fittings
i recommend a brake bias adjuster $75 from summit (wilwood brand)
recommend dual tandem wilwood master cylinder
modify standard park brake cables to suit or buy lokar brand style

running wheels that big i would opt for the 14" rotors and not the 12.19" rotors as they will look small.

wilwood is half price of some the others and good quality

i think thats it

6 pot calipers are a bit overkill and if you want to save some coin just get 4 pot calipers

Thank you for the advice and list of components that I need to get for my pro-tour car. I really appreciate it.

I currently have drag race studs on my car so I think they will be long enough.

I believe that a lot of the parts that you listed come with the kit that I had posted from eBay. I'm going to have to try and track down the rest of the components you had on your list though.

I didn't know that Magnum Force sold the Wilwood brakes systems or I would have checked there as well. I don't recall eBay having the 14 inch rotors so Magnum force may be the solution unless something else pops up.

I agree with you about the size of the rotors with the rims that I'm using.... The aesthetics of the car with my rim choice was a concern of mine which is part of the reason why am using Wilwood to begin with.

 

[benno440]

no worries at all. let me know if there is anything else

 

[Xp29h]

Just to clarify, I certainly would use wilwood! I have them on my charger. However, I would add the power booster instead of the manual. That car will stop much sooner.

 

[super-bee_ski]

YES,
You need power boosted brakes....

Does Wilwood make a power booster??? and if so can somebody point me towards a link that would match up to my car?

Depending on your cam you might want to consider Hydroboost instead of vacuum boosted brakes

Now you have me baffled..... what does the cam have to do with it?

 

[Xp29h]

I don't think Wilwood does! They sell masters but not the booster. That link I posted for www.theramman.com he claimed his booster master combo will brake well down to 10 inches of vacuum. So that should handle a pretty good cam. It's also supposed to be a reissue of a charger booster master setup. Check him out. There have been post about his booster combo. However I do like the thought by Jamiez on hydro boost. I'm not too familiar though..
If I recall the booster kit $495 to your door.

495 for the hydro boost? Or the master cylinder?

 

[JamieZ]

Traditional power brakes use engine vacuum and the booster to provide the braking assist. If you have a more performance cam in the car, you'll have less vacuum at low RPMs and they might not be sufficient to boost the brakes.

Hydroboost uses the power steering pump (which is driven by belts and not vacuum dependent) to provide the braking assist.

I believe Hydroboost systems also tend to be smaller, which might help as some traditional vacuum boosters can be large (although that's probably less of an issue in a B body).

 

[benno440]

hydroboost is awesome but expensive and requires you to have power steering otherwise use a booster and if you have a big cam producing low vacuum you can get a vacuum tank to hook upto your booster to give some more vacuum.

when i priced up a hydroboost unit was looking around the $1k for everything, bought my booster from magnumforce as well with my full wilwood brake kit, i think it is right stuff detailing 68 charger booster or something like that, good priced

07,

The 495 covered the costed of the regular power booster and master cylinder combo shipped. Not a hydro boost!

I looked real quick on rammans site and didn't see hydro boost unit. I know I called Wayne re my brake question. He was very knowledgeable and didn't try to give me a short answer at all. Feel free to call and get his thoughts on what your plans are. He'll give it to you straight for sure. Just plan on being on the phone for a little while. He's got lots of info!

If you do decide to go with a power brake setup, there is a firewall plate that you'll need to have that adapts the booster to the firewall. It is different than the one you have for your manual setup now.

 

[JamieZ]

There are many articles on Hydroboost. An example from this board can be found here:

http://www.forbbodiesonly.com/moparforum/showthread.php?14510-Hydroboost

Looks like the kits are more expensive than traditional power brakes, especially if you do not already have power steering. However if you want boosted brakes and do not have vacuum it's the most common solution.

You might be able to build one from salvage yard parts. I seem to Chevy Astro vans are common donors (a quick google search will turn up several articles about salvage yard astro swaps)

I got the SBS on my 69 roadrunner, but know nothing about them (they were on the car when I bought it) - is there any point to switch them out for Wilwood? Are the calipers interchangeable?

I do got a brake booster.

I'm having a pita to understand the size of rims that will clear them - what should I measure? The size of the brake disc I assume (rim must be larger than the disc...) and how thick the calipers are. I'd love to run 17" in the rear with MT drags on them but since car isn't here yet (eta october) I can't really measure it. Anyone have an opinion in the matter?

btw, looks like this:

[benno440]

most 15" wont fit over 12.19" rotors, 16+ will, 17+ will fit 14" rotors.
will need disc spindle with mount for caliper, wilwood kit will come with rotor, rotor hat and hub

- - - Updated - - -

I bought the 12.19" wilwood kit hoping my centreline 15" wheels would fit, they didnt so i now run BOZE 18" front and 19" back and my discs look a little small inside the wheel, wish i just went 14" straight up

 

[JamieZ]

As for what size wheels fit what size rotors....unfortunately the only way to tell for sure is to test fit them. There is a chart comparing the DrDiff kits that gives you rough estimates:

http://www.doctordiff.com/blog/documentation/disc-brake-kit-comparison/

Stage	Rotor	Caliper	Fits
1	10.95"	OEM	14"
2	11.75"	OEM	Most 15"
3	13"	Cobra	Most 17"
4	13"	Brembo	Some 17" Most 18"

I have a stage 2 kit and it fits my 15" reproduction magnum 500s but there is not a lot of room.
