Front BBK upgrade and wheel bearing install: Step by step w/ pics

[SolidStateS15]

you can buy smaller RCA's, talk to Robert at 935. he's forming a buy for some now.

No worry about running hard on it as the car might not run at all for at least 2 month (1UZ). As for cutting the RCA's I have acces to a machine shop. It should only take few minutes to modify.

Whats the brake pedal travel like after going from single piston calipers to four piston? Just wondering coz im gona be doing a similar upgrade but using Brembos off a Evo VI & have heard of the brake pedal just going straight to the floor when changing to multi piston calipers & using the standard master cylinder in alot of cars

just a little update concerning the rear

the oem rotor have an hole to adjust the e-brake system,so i make an hole in the same place and use the oem parts




like this i can adjust the e-brake system exactly like on the oem rotor
hope it help

No they can't

Great write up. Love the trick to get the rotors off of the hub assembly. Wish I tried that before I gave up replacing my rotors this weekend. Oh well, I'll try again next week now.

I have a question about the directionality of the rotors. When looking at the rotor, which way should the vents face? Looking at your pics, it looks like yours point towards the rear of the car (when turning in the forward direction, air would be pulled in from the center of the rotor and blown out from the cooling fins/vents at the outer edge of the rotor), or should they face forward (so when turning in the forward direction air is pulled from the outer edge of the rotor towards the center of the rotor)?????

For the official record, assuming this is the front left wheel (which I can tell because I can see the tension rod), then this hub & rotor assembly IS setup correctly.

It is nigh on impossible to get them to work the other way (by "forcing in air from the outside in").

Remember your wheels and rotors are in motion. Think of centrifugal force. Remember the merry go round as a kid? The faster you went the harder it tried to fling you off, away from the axis of rotation? Same applies here, just think of turbo chargers, air goes INTO the middle, and comes OUT the Edges.

The rotor vanes if straight, doesn't matter. The rotor vanes if SWEPT need to sweep behind, or lag behind the hubs center when spun in the direction of normal rotation.

This picture below is correct for the front left of the car (and would be for the back left as well)

I know I am bringing this thread back from the dead, but I have a Jim King BBK, both front and rear, en route from Raptor Racing. I have searched but cannot find any significant discussion of this kit and the OEM brake master. Since, as I understand it, total pad surface area has a direct impact on brake feel and effectiveness, I am wondering if anyone has any pad surface area data comparing the OEM pads to the Wilwood Dynalite pads. Also, if anyone has installed the MKIII brake master as part of the Jim King BBK upgrade, I would very much like to hear how that worked out. Any and all input is greatly appreciated.

Use a master cylinder from a 92-95 4runner it's a 100% direct bolt in and has a larger bore as needed to match the larger calipers. This is what I run wih the same BBK kit on my car.
