Brake Questions
Q: Can I put rear disk brakes on my car?
A: Yes, but you will need to graft the rear axle
from an Integra onto your car to make it happen. Another alternative
is to replace the iron rear drums with aluminum drums from the HF
model. This saves weight and works just as well as the Integra rear
disks. You will have to change the rear brake backing plate to a
HF plate to make the aluminum drums fit, but that is a relatively
easy job.
Q: Will the Integra's larger front caliper,
and rotors bolt right on to my CRX?
A: Yes, and the Integra brakes will fit under 13"
wheels.
Q: Should I use slotted or cross-drilled
rotors?
A: For street driving, the plain OEM style rotors
are just fine. Slotted rotors allow the gas that forms between the
pad and the rotors to escape. If you do a lot of hard driving in
hot conditions slotted disks may be good for you. Cross-drilled
also do that and are lighter. But cheap cross-drilled rotors are
subject to cracking. Expensive cross-drilled rotors are cryogenically
treated to prevent cracking.
Q: I am not certain my brake booster is
OK, how do I check I?
A: From the Mk1CRX group on Yahoo groups: To test
the brake booster, try the following procedures: 1.
With the engine off, press the brake pedal several times. Then press
it hard and hold that pressure for 15 seconds. If the pedal sinks,
a brake line, wheel cylinder or master cylinder is faulty. 2.
Start the engine with the pedal pressed. If the pedal sinks slightly,
the booster is working. if the pedal height doesn't vary, the booster
or check valve is faulty. 3. Press the brake pedal
with the engine running. Then stop the engine. If the pedal height
does not vary for 30 seconds the booster is OK. If the pedal rises,
the booster is faulty. 4. With the engine off press the
pedal several times with normal pressure. When the pedal is first
pressed, it should be low. On consecutive applications, pedal height
should gradually rise. If pedal height does not vary, check booster
check valve. The check valve is the thing in the big vacuum line
going to the booster, which is below the master cylinder in the
engine compartment.
Transmission Questions
Q: Who makes a short shifter for the 1st
Gen CRX?
A: I have had both the Pacesetter (terrible) and
the DC sport (great) short shifters in my '87 Si. If you install
a short shifter, the effort to change gears increases. Something
to get used to. The '88 and later short shifters will not fit the
'87 and earlier cars. I used nylon washers in the connecting bolt
of the shifter to smooth shift action.
Q: What is the difference between the cheaper
Phantom Grip Limited Slip Differential (LSD) and the more expensive
LSD from OPM?
A: Shane Portnoff answers: CRE and OPM make a limited
slip, $650. The only difference between theirs and phantom grip
is they put clutch plates in between the differential side gears
and the carrier. The spring package is sandwiched in between the
two side gears putting pressure at the clutch plates, creating "limited
slip". Of course the clutch material will wear out also, but that
is replaceable and probably cheaper than a new differential assembly.
The phantom grip is just the spring package, so the friction created
is between the side gears and the differential carrier. The friction
coefficient must be kind of unpredictable plus the gears and carrier
assembly will eventually wear out. Also there will be ground up
metal inside the trans.
