Our take on the Brembo P4 34/34 108mm Radial Mount Caliper

The Brembo P4 34/34 is a radial-mount four-piston brake caliper for street motorcycles, built from titanium with two 34mm bores per side and a 108mm radial mounting spacing. Radial mounting resists flex under hard braking, so lever feel stays firmer and more consistent than with older axial calipers. It suits riders upgrading the front brake on a sport or naked bike that already has radial fork mounts. It is a serious step up in rigidity and heat handling over stock two-piston sliding calipers, but it needs matching master cylinder and line setup to feel right.

Best forSport and naked bikes with radial fork mountsRiders wanting firmer, more consistent lever feelTrack-day and fast road useFront brake upgrades on performance street bikes
Pros
  • Radial mount reduces caliper flex under load
  • Four 34mm pistons give strong, even pad pressure
  • Titanium body resists heat and corrosion
  • 108mm spacing fits many radial fork legs
  • Well supported pad and seal availability from Brembo
Cons
  • Needs radial fork mounts; not a bolt-on for axial forks
  • Requires matching master cylinder and braided lines to shine
  • Titanium body costs more than aluminum equivalents
  • Pad compound choice matters a lot for street feel
  • Installation and bleeding are best left to a shop

What reviewers say

Owners of radial Brembo calipers generally report a clear gain in lever firmness and braking consistency over stock sliding calipers, with the titanium body holding up well. Most criticism centers on setup: mismatched master cylinders or cheap lines blunt the benefit, and the cost is high for a street bike.

What people mention
  • Lever feelPraisedRiders say the radial mount and four pistons give a firmer, more predictable lever than stock calipers.
  • Heat fadePraisedOwners report less fade during repeated hard braking, helped by the titanium body.
  • SetupMixedThe benefit depends on matching the master cylinder and lines; mismatched parts leave it feeling no better than stock.
  • CostCriticisedBuyers note the titanium construction makes it dearer than aluminum radial calipers with similar performance.
  • InstallationMixedFitting and bleeding are described as a job for a shop rather than a home bolt-on.

Questions and answers

Will this fit my bike?
Only if your fork legs have radial mounts with 108mm spacing and the caliper sits on the left side. Check your fork's mounting pattern before buying; axial-mount forks need adapters or a different caliper.
Do I need a new master cylinder?
Usually yes. The four 34mm pistons move more fluid than many stock masters supply, so a matched radial master cylinder and braided lines give the best lever feel.
Is titanium worth it over aluminum?
Titanium resists heat and corrosion better and looks sharper, but aluminum radial calipers perform closely for less money. Choose titanium if you want durability and finish.
What pads does it use?
It takes Brembo four-pad sets sized for the P4 caliper family. Pick a compound suited to street use, or a track compound if you ride hard on circuit.
Can I install it myself?
It is possible with the right tools and bleeding kit, but brakes are safety-critical. A qualified mechanic should fit and bleed it unless you are experienced.
