Help identifying brake booster please guys....!!

[K9COP]

Hi guys, I'm pretty sure my brake booster has a ruptured diaphragm (OW!). I have a rock hard pedal, no brakes (brakes, but bad/manual only), and the tell-tale vacuum hiss when I apply the brakes, together with some hilarious Prius-pissing-off popping and crackling when braking... 

Problem: I obviously want to replace the booster, but I'm not entirely sure which one it is (part # wise...). Pictures below...

Please see pics. The car was originally (before me) converted from drums/drums to discs/drums. I know the brake discs and calipers are for a '73 Charger, but I think that's a red herring in terms of master cylinder/booster.

This is, I suspect, the original spec master cylinder and booster (very thin) but I am happy with the braking when the booster is functioning correctly, so don't really want to get into changing pedals/brackets/rods etc.

Can someone help with I.D. and part # please? Car is a '69 built, '70 titled 440 four barrel four speed.

Thanks,

K9

p.s. Sorry about the state of the booster, I promise I'll detail the new stuff to look nice too....

I don't think that is from a charger, if you now have disc brakes, time to upgrade  dual diafram booster hemi style , extra vacuum power for brakes and brand new ,
Pirate jacks , direct bolt on , your existing master cylinder will bolt straight up to it

Thank you. I emailed Pirate Jacks, not heard back yet.... the master cylinder has this 'KG 14 3A 71258' cast into the side of it but I can't make that match any casting/part numbers....:



Thanks,

To be honest, that master cylinder doesn't look all that familiar either.

Master Cyl or the booster. Definately replaced at some point. Googlethe numbers and put them in on EBag as well ... ya never know.

Ha! Great minds think alike! Thank you! I just identified the master cylinder as Dorman M71258. More or less correct fitment. I spoke to the previous owner earlier (very helpful and patient chap) who said the booster was from a 1969 Satellite....

This may get me further forward, but as it has a $30 master cylinder in it, I may just bite the bullet and swap the whole lot......

Good idea , because that looks like a drum brake one , disc brake ones are a lot deeper, brakes need the extra fluid the deeper reservoirs hold ,
Avoid dorman or cardone , been there done that  ! Junk , re manufactured and badly
Stainless steel brake company or anyone else with a good name, will bolt straight up, watch the bore size when getting your new one , make sure it's for disc brake car ,
Bench bleed it , mask it up and give it a good coat of cast grey paint, they come bare, and it will rust up in no time

Wayne Brown at theramman.com can help too.  Not cheap but he's a Mopar guy and the quality is 100%.  A lot of useful information on his website too.

Wayne is the best in the brake world market!  As Ghoste said his products are not cheap but he stands behind his work 100%.  I have used his services on my rides and never had any problems or complaints about his work.  When I was installing my master cylinder on my charger I had a simple question for him.  This was at 8pm and I left a message in his voicemail.  Five minutes later he called back and answered my questions.  You pay but you will receive quality service and products!

Wayne is a true Mopar nut he will talk to you for hours it seems about mopar brakes/cars.  He especially loves 69 GTX's.
