RL 4 piston caliper brackets complete (Pic inside)

whats77inaname · 08-08-08, 01:13 PM

Prototype is now complete. It is complete bolt on, nothing to cut. 4 bolts and the bracket (made of cold rolled steel). The rotor is the 11.8" from a 2001 CL, bored to fit our hub. The majority (85%ish) of the pad are on the rotor, and the bracket will be adjusted 2-6mm to bring the caliper down a bit more for more surface contact. I'm waiting for the OEM mounting bolts to come in, and then the bracket will be tapped to fit them.

After everything is tapped next week, I'm taking them to have them powder-coated.

For those that are interested in purchasing the brackets, let me know on this thread, so I can get a running count. If I can go to my guy with a set number of people interested, then I can negotiate a lower price. Right now, he is asking $205/set of 2. After I get them on my car, I'll get pricing so we can start moving forward. For those interested:

I will be providing the brackets and the bolts to mount the bracket to the original caliper mounting locations. You will have to provide a) your own CL rotors (which will need to be bored out and b) the OEM mounting bolts (part number 90107-SJA-000).

With this now done, for those that want a bigger rotor, I can also work on having a bracket made for a 12.2-12.4" rotor.

Cheers!

The only concern I have is once wear starts to set in on that pad, you'll have a 'lip' created by the part of the pad not touching the rotor. How will that effect the functionality of the brake?

I wouldn't imagine that it would be an issue. The piston area is completely on the rotor, so if the pads form a lip, it won't affect braking performance. And if you look at the RL pad, they're almost square anyway, so regardless of what kind of rotor is used, the lip you're mentioning still forms on a completely stock setup, as well.

ok at 205 im up for a set but 1st will this alter you offset?

whats77inaname · 08-08-08, 01:53 PM

Nopers, it doesn't.

emaculate94GS · 08-08-08, 02:38 PM

Will the 16" GS wheels still work with this set-up?

Any reason for the 100% mark-up? In your last thread you had said that these brackets should not cost more than $100 for the pair. I understand you need to receive some royalties here, but for these to double in price is a little odd. Please do not take my curiosity as thread crapping or anything along those lines at all. What sort of GB would we have to get in order to bring the price closer to the $100 mark?

In my last post, I said it shouldn't be $100 b/c that's what he originally told me. Anyone that purchases these aren't paying an increase. You will be paying what he charges me, plus whatever method you choose to ship. I'm not making any money off this. Period. Not one red cent. I covered the R&D out of my pocket, and am passing none of my expenditures on to anyone else. Just trying to help out the community, that's all.

I will try to work on the price with him once I get a working set on my car. I don't want to find out that there's some catastrophic failure and then have that on my conscience. I will also shop the work so that I can bring these to the community at the lowest possible price. Trust me, I'm as cheap as they come, so I'd like to be able to bring at least one low price, quality, after market piece to the community.

how much will this alter the offset of your wheels?

Alperovich · 08-11-08, 06:11 PM

okay, so do that pads fully contact the rotor? or does part of the pad not? b/c if it doesn't touch the rotor that portion of the pad wont wear at all and can and will cause problems (i've seen it, i had a customer who had brake work done, about ~6months prior, the place installed a wrong rotor, long story short, the pads were coming in contact with each other causes a issue).

i was thinknig if the pads don't fully touch the rotor the solution might be to shave part of the pad down so all of it will be touching the rotor.

I agree, just cut out the surface of the pad that doesnt make any contact. Without doing so will cause problems, the brakes could rub, lock, or the pads could contact each other and not contact the rotor, brakes are not to be played with!

I'm not thinking that it will. He's working on making some changes I requested, so when the OEM mounting bolts come in and I visit with him, I'll take some measurements and know for certain.

I'm looking at it, and I don't really see how the pads can touch. The rotors are more than 3/4" wide, and the pads are 1/4" or so thick, so there's 1/4" between the pads. There would have to be an enormous amount of wear for the pads to touch, but shaving them might be an option.

What kind of gain are you expecting, I think we need a more powerful brake booster I could be wrong I dont see what the gain would be with the extra pistons. Can the 4 postions exert more force then the two with the equal amount of booster pressure?

I would be inclined to think so, as I don't know of any BBKs that offer a bigger brake booster as part of their kit and the people that install them indicate there is a noticeable difference.

this is a yes and no type thing. I will have to look when I get home, but there is an equation that measures pressure vs area of the piston, and that gives you your clamping force, depending on the area of the piston it is entirely possible that 4 pistons will out perform 2. smaller area means less force to move, so with the force it takes to move 2, it could take significantly less force to move 4. follow? Once I post the equation you will see what I mean, its hard to explain.

HowStuffWorks "Brakes: Leverage and Hydraulics"

That is along the lines of what I was trying to say.
