Default Wilwood vs Hydroboost

Hello all,

I sent a message out to a hydroboost supplier some time ago and shared with them that I had Wilwood calipers on the car. I was told this combination could work but "I will ask that you be mindful while stopping and stopped at a red light to not keep pushing down on the pedal because the booster will still be assisting in pressures and the Wilwood calipers are not cast and will expand and could bend or brake."

Anyone else heard this or have had issues? I did reach out to Wilwood but no response yet.

I run a Hydroboost system, but not with Wilwood. Can't see their calipers bending or breaking due to hydro boost pressure. Seems kinda weird.
Not like you would need added pressure while already stopped, so pressure would be minimal when stopped. Not sure who's hydro boost system your looking at
But I bought mine thru Hydratech, great to deal with. https://www.hydratechbraking.com
Im sure they would be able to help you on that question.

I had a hyroboost with Wilwood 6 piston brakes - no issues.

BUT -- I did not like it and went to manual brakes. Plus less junk under the hood to deal with and route etc. Many guys have issues with their power steering booster and reservoir quite often with hydroboost.

With brakes like Wilwood you can go bigger in rotors / calipers, getter better bite pads etc and not even know you don't have power assisted brakes.

I would never go back to hydroboost. Love my manual set up around town and on the track.

Thanks for the feedback guys. I don't want to post the company name, just don't think that would the right thing to do but it is a big name in the brake products distribution industry. Currently waiting to hear back from Wilwood.

I didn't want to be spreading misinformation and I did get a reply from Wilwood. It seems the comment made to me by the Hydroboost distributor is not entirely accurate. This from Wilwood:

Thank you for the inquiry with Wilwood Disc Brakes.

The calipers are forged not cast and we’ve had plenty of customers use hydroboost systems with our brakes and be just fine.

The comment by the hydroboost distributor also just doesn't make logical sense. If their concern was pedal pressure being too great and possibly breaking/deforming the caliper, the biggest risk of that happening would be under heavy braking, not while you are stopped at a light. I don't think there's any merit to their claim, and would follow Wilwood's guidance.

I too am surprised by the comment. This comes from a large name distributor of braking systems. I'm not expert but I too would have thought that the pressure would be greatest under hard or panic braking.

Yep 100% correct. I can make a brake hyd line or a wheel cyl. burst if I really stand on the brake pedal in my 2001 Chevrolet 3500 work truck.

Comment was made by a person who failed high school physics.

Five summers now with a hydroboost (recommended by Wilwood) and conversion to Wilwood brakes (6 piston front, 4 piston rear). All good and very happy with improvement.
