Hi all,

Thanks for viewing my post and I hope you can give me your 2 cents on this discussion.

Currently thinking of upgrading my cd5 brake master cylinder but unfortunately I cannot locate any info on the net regarding this upgrade.

Question - Are they any OEM MC that would be interchangeable to the cd5? (1")
if not, would there be any after market ones available?

Thanks your input.

Cheers

 

Not really, at least from what I've seen. What's wrong with your current one?

 

Upgrade as in what exactly?
What are you attempting to accomplish?
Has basic maintenance been done?
Have the components been all checked for proper wear and correct adjustment?
Have you replaced the brake fluid with one of a higher boiling point?
Have you increased brake performance with pads?
Have you maximized grip with stickier tires?
Do you routinely cook the brakes?

Before even touching the MC you will want to do the above to reduce your stopping distances and increase fade resistance.

 

Hey guys,

Brake update was made with Willwood 4 pots with 330cm slot rotors - brake update was made due to engine swap and forced induction.

Currently running standard oem MC but the pressure when applying the brakes are not as strong.

Upgrade as in what exactly? - Master cylinder to 1"?
What are you attempting to accomplish? - to have better bite on the pedal
Has basic maintenance been done? - YES
Have the components been all checked for proper wear and correct adjustment? - YES
Have you replaced the brake fluid with one of a higher boiling point? - DOT 3/4 - standard
Have you increased brake performance with pads? yes with complete brake update package
Have you maximized grip with stickier tires? YES - RE001s
Do you routinely cook the brakes? - no.

Thanks in advance

 

Sorry, we just deal with A LOT of stupid people asking a lot of stupid questions on here. Trying to get a baseline on where you're at, which obviously seems fairly far. Would like to see pictures of your setup!

 

No worries mate! Clearly understand where you're coming from.

Do you know if the DC2R or DC5R brake master would fit in the CD5?

I do have a very old photo (Stock H22a and measuring the turbo)

Please see attached.

Thanks

 

Is this a kit? Front only or rear too? If so Wilwood would have provided information on what MC is to be used. Usually kits from Wilwood, StopTech etc will have a notation on what MC to use, and often times the factory installed MC is fine.

Or is this something you put together yourself?
What size are the pistons in the new calipers?

When changing components of a brake system it must be kept in mind that brakes are a system. Increasing rotor size changes the bias, changing caliper piston area changes the bias. If a large rotor and large piston area is used then the bias will be moved forward. This will reduce total braking power as the system will be unbalanced. It might feel like the car is stopping harder but in reality the distances are increasing.
MC is sized to fulfill the pressure and volume needs of the system.
Is the pedal short and stiff or long and soft?
Are you still running a power booster? If so pump the pedal to deplete any vacuum reserve. With your foot on the pedal is it stiff? When you turn the car on does the pedal drop? If so how much?

MC bore is 1" for ABS Disc/Disc cars and 15/16" for non ABS disc/drum cars. Which car do you have?
Disc/Disc cars already have this.
Not really sure what this means, is the pedal long and soft?
How is it compared to when the car had its stock brake system?

 

Thank you for your reply.

I understand that there are many questions that required to be answered when modifying the brake systems or any modifications overall.

I don't want to be rude but my initial question was very simple and direct and a straight forward reply would be ideal.

Many Thanks

Regards,
