How to Correct Brake Pedal Ratio for Manual Brake Conversion (Brake Booster Delete)

Are you Thinking about deleting the stock brake booster in your track car? Have you run out of clearance with your engine swap and need to free up some space? In this episode I’m going to show you how to correct your brake pedal ratio after converting to manual brakes without a brake booster so that you can stop your car without needing the legs of Hercules to depress the pedal.

Great vid mate.

Great Info and very well presented! Your video is a God send for the rock hard pedal on my 1967 Mustang with manual braking system. Can't wait to get started and get my pedal ratio back to where it needs to be. Going with a new Wilwood 7/8" or 5/16" bore, new correct pedal and new prop valve. Thanks for sharing young sir. Cheers and blessings from Motown Usa.

excellent video, very helpful. Thanks for posting!!!

[@justanidiotwithcars]

honestly quality content, brother, keep it up!

[@MODIFYUP]

Thank you for your kind words!

[@clef998s3]

I have a Silvia as well with the same style master cylinder/ brake booster delete. About how much did you move it up exactly because I’m going to be doing the same thing to get the pedal feel I want. Great video and thank you for the information!

[@husseinpoliphilo]

I have a s14 as well. Can you give the info on how much I need to move my holes if I have a chasebays delete and also where you went up on the brake pedal.

[@unclassifiedjz6885]

5.7 not bad i know chasebays made one that a 6:1 and its a dual piston.. but regardless gooshit for doing your own calculations and work!

[@somegi9]

thanks for this! stoked at the ITB CADET!

[@MODIFYUP]

Haha thanks. Yes will do a full video on my s13 shortly! Stay tuned

[@marshallclay4978]

@Tyler Martin Thanks for your reply. I got to the site on google and Im in the hacking process atm. Seems to take quite some time so I will get back to you later with my results.

[@BadBillyJack]

I see that Funky Garage banner. whaddup.

[@MODIFYUP]

Yes sir!

[@jeff666p]

Would a 5.5:1 ratio with a 1" bore be to stiff?

[@jesperdahl1486]

I am really curious as to how you retain braking on one front wheel, and one rear wheel, when you loose one circuit on a dual master cylinder, since both front brakes are on one circuit, and both rear brakes are on the other circuit (unless you have a Volvo from 66 on, until unknown year, because they have dual circuit front calipers, so you retain both front brakes (but only on two of four pistons) and one rear brake, when you loose a circuit)

[@MODIFYUP]

Hi Jesper, Good question. In my case which is a dedicated track car I do not have a diagonally split tandem system nor a twin master system. Traditionally a motorsport system is never diagonally split however 2 master cylinders are used, 1 master for the front circuit and 1 for the rear circuit so if a failure was to occur there would still be brake force on 1 axle wether it be the front or rear. A single master system does not have the same redundancy as a twin master or a tandem master system.

[@Manuqtix.Manuqtix]

I have a question. What do you need to do a remote brake booster conversion?

[@nobodynoone2500]

depends on your master cyl, i'd just do a cheap wilwood setup
