Hydroboost with Willwood Master
 

I'm buying a hydroboost setup and need to know which willwood master cylinder works with the hydroboost. Summit has about 10 different willwood master cylinders with different bore sizes.

What bore size do I need to order?



Rich

what brakes do you have?

Complete 4 wheel disc Baer

i think a 1 inch or 1-1/8 bore woul dbe right about what you would want.
are they pbr calipers? alcons? 4 pisotn, 6 piston?

I have the 1 1/8 Wilwood MC on my car. I have 6 piston Baer on all 4 and a Hydratech hydroboost unit. Paul from Hydratech recommended a master with 1 1/8 bore. The brakes work fantastic!!:yes:

Thanks for the reply. I just spent 15 minutes on hold with CPPP to find out it's 1-1/8" ;)

Thank you,


Rich

260-8556 for natural, add a (P) suffix for the polished version.

We have one on the shelf in polished

Hello
I have a question
I just got my hydraboost and 1 1/8 bore Wilwood master.
But it feels like the pushrod in between the master and the booster is too short.
when I push on the pedal after about an inch of movement the pedal has a harder feel to it. It's like the pushrod doesn't meet the master for an even feel thought the motion.
Is this normal?

Thanks
Rob

What resivor are you using?

Wilwood's dual, non remote reservoir, Alloy master cylinder
part # Wilwood 260-8556P

thanks

Boy your not kidding Rich, I called CPP today and was on hold forever. when the guy finally got on the phone he didn't have a clue what hydroboost was. I was alway told they have pretty bad customer service skills. I'm hoping it gets better if there the only people we can go to for parts.

Hydroboost Response
 

I just recently purchased a hydroboost system and was able to email Paul at Hydratech before I chose to buy. I know that my G-Body with hydroboost 3033 with the Wilwood dual master cyclinder and Paul said that I need to use a short pushrod with a spacer bullet that comes with the Wilwood master cylinder.I'll give an update when I give a chance. Paul also recommended talking to Mark at SC&C (Savitski Customs) who was extremely helpful.:thumbsup:
