Not enough engine vaccuum to run power brakes? No problem! This new electric E-Booster by Classic Performance Products part #6474EBK-SB that fits GM 1964-1972 A-bodies (Olds Cutlass/442, Buick Skylark/GS/GSX, Pontiac LeMans/GTO, Chevrolet Chevelle), 1968-1974 X-bodies, and the 1967-1969 F-body (Camaro & Firebird). It uses a Bosch Gen2 electromechanical iBooster, married to CPP's aluminum body 1.125" bore master cylinder, and includes a custom billet aluminum mounting bracket and all neccessary hardware and wiring. Follow along as I install this kit into my 1971 Oldsmobile Cutlass S, so that in a few weeks when the hydraulic roller cammed 482 big block Olds goes in, I don't have to worry about how to stop the beast.

According to Classic Performance Products technical department, this booster will work fine with front disc and rear drum brakes or disc-disc setups. It includes an adjustable proportioning valve. It also is supposed to work well with Corvette C5/C6 twin piston front brake conversions on the A-body.
0:25 The starting point, factory discs up front & drum brakes on the rear
2:37 Why I want electric assist power brakes
3:06 Braking force required increases with the square of speed
4:18 New braided brake lines from Kore3
4:50 A peek into the new larger Corvette front brakes going on in a few weeks
5:50 If you have an engine that does not have enough vacuum to run vacuum assist power brakes, here are 3 options: manual brakes, hydraulic assist, or electric assist
8:10 Showing the CPP part #6474EBK-SB "Electric Brake Booster Kit for 1964-74 AFX" (linked below)
10:36 Beginning the istallation
13:21 Mounting the CPP adapter bracket to the firewall
13:52 my first blunder that wasted 1-1/2 hours
14:35 putting in the mounting bracket to booster bolts are not bad!
15:06 Wiring up the iBooster is simple
16:14 All new steel brake lines from The Right Stuff "69 GTO, Skylark & Cutlass Power Fr Kisc Conversion R Drum Pre-Bent Brake Lines - AOP69H2" & why the word "conversion" is important here
17:07 The snags I had putting parts in
19:29 Finishing showing the installed 3 wires from the iBooster
20:30 Bench bleeding the new master cylinder
20:58 New stock brake hoses on the stock 11" front disc brakes. The new braided front lines are for the Corvette C5/C6 front calipers and won't fit these stock brakes
21:35 Major blunder #2: we re-bled the master cylinder when we were not getting ANY fluid out of the bleeders. We discovered LATER that it's because the brake booster drive rod was NOT seated into the drive rod on the master cylinder!
23:28 successfully bleeding the brakes
24:51 Showing and hearing the new electric power assist working
25:58 Brooks Brothers "$130 shop rag" LOL
26:45 Test Drive!
28:25 A summary and my closing thoughts on the car & the system
30:01 A sneak peek into what's next with the brakes!
30:20 Twin electric fans video 5/3/2025!
30:34 Outro with montage with original music from Aq Xico
