what brake booster?

[krohny]

was wondering if anyone knows what brake booster/master i could use in an LA lancer if i were to fit silvia (s13) front brakes?
im not entirely sure how the booster and master side of things work..

thanks in advance!

are the silvia front brakes standard single piston calipers....or the 4-psiton sports type???

[krohny]

Good question.. just single piston, they are the smallest ones that came on a Silvia, my mate is giving them to me so I don't know much about them

[Scorpma82]

being the smaller (in comparison to the 4 piston) of the 2 setups......you should be OK with the standard cylinder and booster setup......but you may experience a slightly longer pedal

As in the standard lancer booster/master?

[Scorpma82]

yeah......your not increasing the volume of the front caliper all that much....so pedal travel wont change much either.....your biggest change is the effeciency.....purely because u'll be running on a larger, ventilated rotor.......so it has the ability to stay cooler....longer

[krohny]

Too easy, aside from the fact it doesn't have a booster at all, but I can find one easy enough. Thanks for your help!

no worries......

you may not need a booster - I removed the booster off my sigma when it was built as a hillclimb car way back in 1999
that uses 4 wheel discs ( starion )
I went down to a 3/4" master cylinder fitted an inline presure adjuster to the rears and never looked back
the pedal is firm but has better feel than the boosted brakes

in fact its quite easy to brake hard and feel what the brakes are doing ,so its easy to hold them just off locking

yeah very effective cheaterparts......but those adjustable pressure adjusters aren't legal....at least the last i heard they weren't

mine is for the track only so its ok I should have made up a peddle box with 2 masters in the first place
but the adjustable presure to the rear did the job - that way you get brake realy standing on them and have all wheels just short of locking - or adjust them to do so
however for the road it not legal to fit bigger brakes or 4 wheel discs with out an engineers report but we do
